* misc: consolidate macro style USAGE_HELP_OPTIONSRuediger Meier2017-06-291-2/+2
| | | | | | | | | changed in include/c.h and applied via sed: sed -i 's/fprintf.*\(USAGE_MAN_TAIL.*\)/printf(\1/' $(git ls-files -- "*.c") sed -i 's/print_usage_help_options\(.*\);/printf(USAGE_HELP_OPTIONS\1);/' $(git ls-files -- "*.c") Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: introduce print_usage_help_options()Ruediger Meier2017-06-271-2/+1Star
| | | | | | | | | | | | Consolidate --help and --version descriptions. We are now able to align them to the other options. We changed include/c.h. The rest of this patch was generated by sed, plus manually setting the right alignment numbers. We do not change anything but white spaces in the --help output.

* textual: add a docstring to most of the utilitiesBenno Schulenberg2015-01-061-0/+3
| | | | | | | | | 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>

* ionice: add the way to specify the target processes with pgid and uidMasatake YAMATO2014-02-171-22/+48
| | | | | | | | | | | | | ioprio_get and ioprio_set system call accept not only process ID but also process group ID(pgid) and user ID(uid) to specify the target process(es). However, ionice command accepts only process ID. With this patch a user can specify the target processes with pgid(-P option) and uid(-u option).

| | | | | | | | | | | | | | | | | $ ionice 123 none: prio 4 none: prio 4 It calls ioprio_get(0x1, 0) and ioprio_get(0x1, 123), because the code does not check it the "-p" options was specified. The proper command line syntax is: $ ionice -p 123 and the ioprio_get() should be called only once. Signed-off-by: Karel Zak <kzak@redhat.com>

* build-sys: provide alternatives for err, errx, warn and warnxFabian Groffen2011-02-141-2/+1Star
| | | | | | | | Solaris lacks err, errx, warn and warnx. This also means the err.h header doesn't exist. Removed err.h include from all files, and included err.h from c.h instead if it exists, otherwise alternatives are provided. Signed-off-by: Fabian Groffen <grobian@gentoo.org>

| | | | | | | | | | | | | This patch replaces a few functions used throughout the source: * Renames getnum (from schedutils) to strtol_or_err * Moves strtosize (from lib/strtosize.c) * Moves xstrncpy (from include/xstrncpy.h) * Adds strnlen, strnchr and strndup if not available (remove it from libmount utils) A few Makefile.am files were modified to compile accordingly along with trivial renaming in schedutils source code.

* ionice: non-cryptic error message when ionice can't execvpÆvar Arnfjörð Bjarmason2010-05-061-1/+1
| | | | | | | | | | | | | | | | Previously ionice would reply like this when it couldn't find the command to execute: $ ionice -c 3 does-not-exist ionice: execvp failed: No such file or directory Getting that message from cron because you haven't set the right $PATH makes it hard to track down the problem. Now it says: $ ionice -c 3 does-not-exist ionice: executing does-not-exist failed: No such file or directory Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com>

* ionice: Allow setting the none classJakob Unterwurzacher2009-05-271-2/+4
| | | | | | | | | | Allow users to set the "none" class on processes. Using the none class has the distict advantage that the io priority is inherited from the cpu nice level.

* ionice: add strtol() checks, cleanup usage text and man pageKarel Zak2008-09-061-18/+40
| | | | | | | | | | | | | | | | | | | * cleanup usage() output * check strtol(); don't ignore wrong command line options The original ionice design was a little broken, because it was possible to specify a PID and also a COMMAND: ionice -c2 -p 123 /bin/foo but the command /bin/foo was executed without requested scheduling class. That's stupid behaviour. Now you have to use "-p PID" **or** COMMAND, but not both. Nothing is ignored and all options are checked. Signed-off-by: Karel Zak <kzak@redhat.com>

* ionice: add -t optionLubomir Kundrak2008-06-161-4/+10
| | | | | | | | | | | | | | | | | | | | | | | This patch allows "tolerant" behavior, i.e. proceeding even if priority could not be set. This might be of use in case something (selinux, old kernel, etc.) does not allow the requested scheduling priority to be set. This could be to some extend done as follows: ionice -c3 command || command but the downside is that one could not really tell if what failed was setting priority or command itself, which could result in duplicate command run. This patch solves the situation, so that user can do ionice -t -c3 command Addresses-Red-Hat-Bugzilla: #443842 Signed-off-by: Lubomir Kundrak <lkundrak@redhat.com> Signed-off-by: Karel Zak <kzak@redhat.com>
