+                       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard.  To achieve this, non-free programs must
+be allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at least
+    three years, to give the same user the materials specified in
+    Subsection 6a, above, for a charge no more than the cost of
+    performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+^L
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+^L
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or
+your school, if any, to sign a "copyright disclaimer" for the library,
+if necessary.  Here is a sample; alter the names:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the

+libblkid - a library to handle device identification and token extraction
+
+Basic usage is as follows - there are two normal usage patterns:
+
+For cases where a program wants information about multiple devices, or
+expects to be doing multiple token searches, the program should
+directly initialize cache file via (second parameter is cache
+filename, NULL = default):
+
+	blkid_cache cache = NULL;
+	if (blkid_get_cache(&cache, NULL) < 0)
+		/* error reading the cache file, not really fatal */
+
+Note that if no cache file exists, an empty cache struct is still
+allocated.  Usage of libblkid functions will use the cache to avoid
+needless device scans.
+
+The model of the blkid cache is that each device has a number of
+attributes that can be associated with it.  Currently the attributes
+which are supported (and set) by blkid are:
+
+	TYPE		filesystem type
+	UUID		filesystem uuid

+
+
+How to use libblkid?  Normally, you either want to find a device with
+a specific NAME=value token, or you want to output token(s) from a
+device.  To find a device that matches a following attribute, you
+simply call the blkid_get_devname() function:
+
+	if ((devname = blkid_get_devname(cache, attribute_name, value))) {
+		/* do something with devname */
+		string_free(devname);
+	}
+
+The cache parameter is optional; if it is NULL, then the blkid library
+will load the default blkid.tab cache file, and then release the cache
+before function call returns.  The return value is an allocated string
+which holds the resulting device name (if it is found).  If the value
+is NULL, then attribute_name is parsed as if it were
+"<attribute_name>=<value>"; if it cannot be so parsed, then the
+original attribute_name is returned in a copied allocated string.
+This is a convenience to allow user programs to want to translate user
+input, whether it is of the form: "/dev/hda1", "LABEL=root",
+"UUID=082D-26E3", and get back a device name that it can use.
+
+Alternatively, of course, the programmer can pass an attribute name of
+"LABEL", and value of "root", if that is more convenient.
+
+Another common usage is to retrieve the value of a specific attribute
+for a particular device.  This can be used to determine the filesystem
+type, or label, or uuid for a particular device:
+
+	if ((value = blkid_get_tag_value(cache, attribute_name, devname))) {
+		/* do something with value */
+		string_free(value);
+	}
+
+If a program needs to call multiple blkid functions, then passing in a
+cache value of NULL is not recommended, since the /etc/blkid.tab file
+will be repeatedly parsed over and over again, with memory allocated
+and deallocated.  To initialize the blkid cache, blkid_get_cache()
+function is used:
+
+	if (blkid_get_cache(&cache, NULL) < 0)
+		goto errout;
+
+The second parameter of blkid_get_cache (if non-zero) is the alternate
+filename of the blkid cache file (where the default is
+/etc/blkid.tab).  Normally, programs should just pass in NULL.
+
+If you have called blkid_get_cache(), you should call blkid_put_cache()
+when you are done using the blkid library functions.  This will save the
+cache to the blkid.tab file, if you have write access to the file.  It
+will also free all associated devices and tags:
+
+	blkid_put_cache(cache);

+.SH DESCRIPTION
+The
+.B blkid
+program is the command-line interface to working with
+.BR libblkid (3)
+library.  It can determine the type of content (e.g. filesystem, swap)
+a block device holds, and also attributes (tokens, NAME=value pairs)
+from the content metadata (e.g. LABEL or UUID fields).
+.PP
+.B blkid
+has two main forms of operation: either searching for a device with a
+specific NAME=value pair, or displaying NAME=value pairs for one or
+more devices.
+.SH OPTIONS
+.TP
+.BI \-c " cachefile"
+Read from
+.I cachefile
+instead of reading from the default cache file
+.IR /etc/blkid.tab .
+If you want to start with a clean cache (i.e. don't report devices previously
+scanned but not necessarily available at this time), specify
+.IR /dev/null .
+.TP
+.B \-g
+Perform a garbage collection pass on the blkid cache to remove
+devices which no longer exist.
+.TP
+.B \-h
+Display a usage message and exit.
+.TP
+.B \-l
+Look up one device that matches the search parameter specified using
+the
+.B \-t
+option.  If there are multiple devices that match the specified search
+parameter, then the device with the highest priority is returned, and/or
+the first device found at a given priority.  Device types in order of
+decreasing priority are Device Mapper, EVMS, LVM, MD, and finally regular
+block devices.  If this option is not specified,
+.B blkid
+will print all of the devices that match the search parameter.
+.TP
+.B \-L " label "
+Look up one device that uses the label (same as: -l -o device -t
+LABEL=<label>).  This look up method is able to reliable use /dev/disk/by-label
+udev symlinks (depends on setting in /etc/blkid.conf). Avoid to use the
+symlinks directly. It is not reliable to use the symlinks without verification.
+The \fB-L\fR option is portable and works on systems with and without udev.
+.TP
+.B \-u " list "
+Restrict probing functions to defined (comma separated) list of "usage" types.
+Supported usage types are: filesystem, raid, crypto and other. The list can be
+prefixed with "no" to specify the usage types which should be ignored. For example:
+.sp
+  blkid -p -u filesystem,other /dev/sda1
+.sp
+probes for all filesystems and others (e.g. swap) formats, and
+.sp
+  blkid -p -u noraid /dev/sda1
+.sp
+probes for all supported formats exclude RAIDs. This option is useful with
+\fB-p\fR only.
+.TP
+.B \-U " uuid "
+Look up one device that uses the uuid. For more details see the \fB-L\fR option.
+.TP
+.BI \-o " format"
+Display
+.BR blkid 's
+output using the specified format.  The
+.I format
+parameter may be:
+.RS
+.TP
+.B full
+print all tags (the default)
+.TP
+.B value
+print the value of the tags
+.TP
+.B list
+print the devices in a user-friendly format
+.TP
+.B device
+print the device name only
+.TP
+.B udev
+vol_id compatible mode; usable in udev rules
+.RE
+.TP
+.BI \-O " bytes"
+Probe at the given offset (only useful with \fB-p\fR).
+.TP
+.BI \-p
+Switch to low-level probing mode (bypass cache)"
+.TP
+.BI \-s " tag"
+For each (specified) device, show only the tags that match
+.IR tag .
+It is possible to specify multiple
+.B \-s
+options.  If no tag is specified, then all tokens are shown for all
+(specified) devices.
+In order to just refresh the cache without showing any tokens, use
+.B "-s none"
+with no other options.
+.TP
+.BI \-S " bytes"
+Overwrite device/file size (only useful with \fB-p\fR).
+.TP
+.BI \-t " NAME" = "value"
+Search for block devices with tokens named
+.I NAME
+that have the value
+.IR value ,
+and display any devices which are found.
+Common values for
+.I NAME
+include
+.BR TYPE ,
+.BR LABEL ,
+and
+.BR UUID .
+If there are no devices specified on the command line, all block devices
+will be searched; otherwise only the specified devices are searched.
+.TP
+.B \-v
+Display version number and exit.
+.TP
+.BI \-w " writecachefile"
+Write the device cache to
+.I writecachefile
+instead of writing it to the default cache file
+.IR /etc/blkid.tab .
+If you don't want to save the cache to the default file, specify
+.IR /dev/null.
+If not specified it will be the same file as that given by the
+.B \-c
+option.
+.TP
+.I device
+Display tokens from only the specified device.  It is possible to
+give multiple
+.I device
+options on the command line.  If none is given, all devices which
+appear in
+.I /proc/partitions
+are shown, if they are recognized.
+.SH "RETURN CODE"
+If the specified token was found, or if any tags were shown from (specified)
+devices, 0 is returned.  If the specified token was not found, or no
+(specified) devices could be identified, an exit code of 2 is returned.
+For usage or other errors, an exit code of 4 is returned.

+.SH NAME
+libblkid \- block device identification library
+.SH SYNOPSIS
+.B #include <blkid/blkid.h>
+.sp
+.B cc
+.I file.c
+.B \-lblkid
+.SH DESCRIPTION
+The
+.B libblkid
+library is used to identify block devices (disks) as to their content (e.g.
+filesystem type) as well as extracting additional information such as
+filesystem labels/volume names, unique identifiers/serial numbers, etc.
+A common use is to allow use of LABEL= and UUID= tags instead of hard-coding
+specific block device names into configuration files.
+.P
+Block device information is normally kept in a cache file
+.I /etc/blkid.tab
+and is verified to still be valid before being returned to the user
+(if the user has read permission on the raw block device, otherwise not).
+The cache file also allows unprivileged users (normally anyone other
+than root, or those not in the "disk" group) to locate devices by label/id.
+The standard location of the cache file can be overridden by the
+environment variable BLKID_FILE.
+.P
+In situations where one is getting information about a single known device,
+it does not impact performance whether the cache is used or not (unless you
+are not able to read the block device directly).  If you are dealing with
+multiple devices, use of the cache is highly recommended (even if empty) as
+devices will be scanned at most one time and the on-disk cache will be
+updated if possible.  There is rarely a reason not to use the cache.
+.P
+In some cases (modular kernels), block devices are not even visible until
+after they are accessed the first time, so it is critical that there is
+some way to locate these devices without enumerating only visible devices,
+so the use of the cache file is
+.B required
+in this situation.
+.SH AUTHOR
+.B libblkid
+was written by Andreas Dilger for the ext2 filesystem utilties, with input
+from Ted Ts'o.  The library was subsequently heavily modified by Ted Ts'o.
+.SH FILES
+.TP
+.I /etc/blkid.tab
+Caches data extracted from each recognized block device.
+.SH AVAILABILITY
+.B libblkid
+is part of the util-linux-ng package since version 2.15 and is available from
+ftp://ftp.kernel.org/pub/linux/utils/util-linux-ng/.
