* textual: add a docstring to most of the utilitiesBenno Schulenberg2015-01-061-0/+4
| | | | | | | | | This adds a concise description of a tool to its usage text. A first form of this patch was proposed by Steven Honeyman (see http://www.spinics.net/lists/util-linux-ng/msg09994.html). Signed-off-by: Benno Schulenberg <bensberg@justemail.net>

* setarch: Fix ppc64le architecturesAnton Blanchard2014-04-071-0/+6
| | | | | | | setarch currently fails on ppc64le because it tries to use big endian architecture names. Fix it. Signed-off-by: Anton Blanchard <anton@samba.org>
* setarch: prefer preprocessor rather than autotools checkSami Kerola2013-08-011-11/+11
| | | | | | | It seems to be pointless to spend time in ./configure phase when preprocessor has to perform #ifndef check anyway. Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* setarch: do not use -1 as array index [cppcheck]Sami Kerola2012-06-091-3/+3
| | | | | | | | | Negative array index does technically work, but looks awkward and can confuse static analyser such as cppcheck. [sys-utils/setarch.c:267]: (error) Array index -1 is out of bounds Signed-off-by: Sami Kerola <kerolasa@iki.fi>

* fstrim, setarch: replace error() with err()Francesco Cosoleto2011-06-081-9/+8Star
| | | | | | | | | | This should improve a bit the portability as error() is a GNU extension and util-linux provides fallbacks for err.h functions. Fix compilation with icc, broken due to a reference to `__builtin_va_arg_pack' in error.h using the -gcc default option. Signed-off-by: Francesco Cosoleto <cosoleto@gmail.com>
* move struct option to .rodataKarel Zak2011-03-031-1/+1

* setarch: provide backwards compatibilityDmitry V. Levin2008-04-161-1/+1
| | | | | | | | | | | | | | | | | | | | | The getopt_long(3) use introduced by commit 8df90dec2bfd8c876ddd4cea010f40550d4e24aa broke backwards compatibility. Old behavior: $ i386 uname -m i686 New behavior: $ i386 uname -m i386: invalid option -- m Linux Traditional method to fix it is to disable program arguments reordering by prefixing getopt_long's optstring with '+' character.

* setarch: fix compiler warningLaMont Jones2007-09-231-1/+1
| | | | | | | NULL is not 0L. It's (void*)0. Passing that as a parameter to a function that takes an unsigned long results in a warning about the lack of a cast. Signed-off-by: LaMont Jones <lamont@debian.org>

* setarch: add --3gb option fot compatibility with Debian linux{32,64} commandKarel Zak2007-08-271-0/+8
| | | | | | | | | | | | Debian had a pre-existing linux{32,64} command which supported only --3gb and --4gb. Adding support for those options allows setarch to replace that package.
