* 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: consolidate all --help option descriptionsRuediger Meier2017-06-271-2/+3
| | | | | | | | Now we are always using the same text also for commands which had still hardcoded descriptions or where we can't use the standard print_usage_help_options macro. Signed-off-by: Ruediger Meier <ruediger.meier@ga-group.nl>
* misc: introduce print_usage_help_options()Ruediger Meier2017-06-271-1/+0Star
| | | | | | | | | | | | 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.

* taskset: don't use zero PID in messagesKarel Zak2017-02-101-7/+14
| | | | | | | | The pid 0 is technically correct, but very confusing for end users. Use getpid() in the messages. Addresses: https://github.com/karelzak/util-linux/issues/413 Signed-off-by: Karel Zak <kzak@redhat.com>
* Use --help suggestion on invalid optionKarel Zak2016-12-191-2/+1Star
| | | | | | | | The current default is to print all usage() output. This is overkill in many case. Addresses: https://github.com/karelzak/util-linux/issues/338 Signed-off-by: Karel Zak <kzak@redhat.com>
* 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>

* schedutils: don't apply -a without -pDaniel Stodden2013-03-261-1/+1
| | | | | | | | The unsuspecting user might use taskset -a mask command. Behavior then is to exec with no affinity applied at all. Better handled by ignoring all_tasks if no pid was given. Signed-off-by: Daniel Stodden <daniel.stodden@gmail.com>

* taskset: use appropriate variable type [cppcheck]Sami Kerola2012-02-081-1/+1
| | | | | | [schedutils/taskset.c:182]: (style) Checking if unsigned variable 'ncpus' is less than zero. Signed-off-by: Sami Kerola <kerolasa@iki.fi>
* cpuset: add option to allow cpulist_parse() to failHeiko Carstens2011-08-151-1/+1
| | | | | | | | | | | | | This is a preparation patch for chcpu. If a cpu should be added to a cpu_set where the cpu doesn't fit into the cpu_set this got silently ignored. Since the cpu-list is user space provided it should be checked if cpus are specified that are completely out of range of the system. In order to do that add a parameter which specifies if cpulist_parse() should fail if it parses a cpu-list with "impossible" cpus. The current callers have been converted so they behave like before.

* taskset: make threads awareDavidlohr Bueso2011-05-111-47/+100
| | | | | | | | | | | | | | | | | | | | | | | Add a new '-a' option to view/modify the CPU affinity for an entire group of threads belonging to a given PID. We create two new functions, print_affinity() and do_taskset() for code simplification. Example: zeus@jilguero:~/src/util-linux/schedutils$ ./taskset -a -p 01 3142 pid 3142's current affinity mask: 2 pid 3142's new affinity mask: 1 pid 3164's current affinity mask: 2 pid 3164's new affinity mask: 1 pid 854's current affinity mask: 2 pid 854's new affinity mask: 1 [kzak@redhat.com: - clean up - move variables to struct taskset] Signed-off-by: Davidlohr Bueso <dave@gnu.org> Tested-by: Jonathan Gonzalez <zeus@gnu.org> 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>

* lib: [strutils] general purpose string handling functionsDavidlohr Bueso2010-11-231-2/+2
| | | | | | | | | | | | | 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.

* taskset: independent of hardcoded NR_CPUS max.Cliff Wickman2007-06-191-33/+168
| | | | | | | | | | | | | | | | | | | | This patch makes the taskset command independent of the system's maximum number of cpus (CONFIG_NR_CPUS). The maximum for CONFIG_NR_CPUS is a moving target. With this patch the size of the systems's cpumask_t is gotten from sched_getaffinity(2). This patch uses variable length bitmasks borrowed from Paul Jackson's variable size bitmask routines (hence I kept his copyright notice). This replaces the use of the glibc CPU_SETSIZE, CPU_SET, CPU_ZERO and CPU_ISSET macros which depend on a hardcoded size for cpu_set_t. (also fixes one little nit: the -V option is "-v" in the built-in help, so changed the built-in help) Signed-off-by: Cliff Wickman <cpw@sgi.com> Signed-off-by: Karel Zak <kzak@redhat.com>
