To assist translators, the help lines are split so that each translation
chunk has one option. This gives bonus of if we add or change an option,
only that option remains untranslated rather than the entire help block.

Library systemd-login offers possibility to display
name of a systemd slice unit for specific pid.
This patch adds output option "slice" which will
show name of systemd slice unit.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
Sometimes with libselinux present but SELinux inactive
the context reported is "unconfined" which contains an
embedded newline. This then causes misalignment of any
subsequent data. So, ps will now protect against that.

Previously the libselinux support was present
in the sources, but disabled with a preprocessor
condition (#if 0).
From now the libselinux support can be enabled with
the --enable-libselinux switch available
in the configuration script. That way is more
flexible than local patches modifying the condition
value from 0 to 1.
ps : This patch removes sd_ prefix from recently added systemd output options
to let them look more tied with the system.
Patch does not change behaviour of these options, only modifies their
representation to user.
Library systemd-login offers possibility to display
name of seat for a session on multi-seat systems.
This patch adds output option "sd_seat" which will
show name of seat or "-", when name of seat can not
be determined, but "seat0" should always exist.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
Library systemd-login offers possibility to display
name of systemd user unit for specific pid. Note that not all
processes are part of a user unit.
This patch adds output option "sd_uunit" which will
show name of user unit or "-", when process does not belong
to any user unit. This is similar to "sd_unit" but applies
to user units instead of system units.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
Library systemd-login offers possibility to display
the name of the VM or container which process belongs to.
This patch adds output option "sd_machine" which will
show machine name or "-" when the name can not be determined.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
Library systemd-login offers possibility to display the Unix
user identifier of the owner of the session of a process.
This information will also be displayed for user processes which
are shared between multiple login sessions of the same user,
where sd_session will be blank.
This patch adds output option "sd_ouid" which will show
user UID or "-", when there is no owner for a process.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option
to enable this option.
Library systemd-login offers possibility to display name
of login session for specific pid.
Note that not all processes are part of a login session
(e.g. system service processes, user processes that are shared
between multiple sessions of the same user, or kernel threads).
This patch adds output option "sd_session" which will
show name of session or "-", when process does not belong
to any session.
To maintain compatibility with non-systemd systems,
procps must be configured with --with-systemd option

Library systemd-login offers possibility to display
name of a systemd unit file for specific pid. Note that
not all processes are part of a system unit/service
(e.g. user processes, or kernel threads).
This patch adds output option "sd_unit" which will
show name of systemd unit or "-", when process does not
belong to any unit.
To maintain compatibility with non-systemd systems,

Each process in Linux has a /proc/<pid>/ns directory which contains
symbolic links to pipes that identify which namespaces that process
belongs to. This patch adds support for ps to display that information
optionally.

The entire tree's polluted with inappropriate trailing
whitespace. This commit rids our environment of all of
those useless keystrokes. Unfortunately, it sure ain't
a permanent solution and requires every contributor to
instruct their editor(s) to prevent or eliminate them.
Plus it's strongly recommended we all insert something
like what's shown below to our '.gitconfig' file so as
to provide at least some warnings when we try to apply
any patches (git am) that do contain the #@!%& things!

The “.I\-aux” syntax is broken (missing space): as a result, the hyphen

Since the ps command handles signals with it's own handler, it doesn't create
core files when something wrong happens. The attached patch restores the ps
command ability to create core files by calling the default handler once we
print our custom message. The original RH's workaround masked SIGABRT and
SIGSEGV signals and that would conflict with the original intention of the
custom signal handler and also with the filtering patch I sent in my previous
email. Moreover, this solution generates core for all relevant signals (SIGFPE,
etc.).

The UNIX and POSIX standards require that user and
group names be printed as decimal integers when there
is insufficient room. This has led to a constant
stream of bug reports.
With this commit, long names will be truncated and
displayed with a trailing visual clue.
To avoid truncation. the UNIX and POSIX way to change
column width is to rename the column:
ps -o pid,user=CumbersomeUserNames -o comm
The easy way is to directly specify the desired width:
ps -o pid,user:19,comm

This commit restores the missing space between command
lines and the environment when the later is being
displayed. Below is a brief history of that elusive
character.
commit bb4f08ba29
Date: Thu Aug 11 07:42:14 2011 +1000
The ps program was altered for improved args/comm
compliance. At this time, the needed space was
present due to a buglet in the new library
read_unvectored function used by fill_cmdline_cvt.
commit a5881b5a4e
Date: Thu Dec 8 10:19:38 2011 -0600
The trailing space was eliminated so that the
file2strvec and fill_cmdline_cvt returned
command lines contained no trailing space.
However, this created a buglet when control group
hierarchies were displayed and the final cgroup
was empty.
This is also where the undetected ps buglet was
created.

Under certain circumstances, using abort() when either make check
or make distcheck puts ps into an infinite loop around the
function catastrophic_failure() in ps and the C library raise
and abort functions.
Using exit removes this problem and does almost the same thing.
This code currently uses error_at_line() from error.h, so pull it in.
Long term, this might get moved to c.h as a local helper on err.h,
but I have no idea.

Ps command does not display the nice value for processes with the SCHED_BATCH
scheduler policy, only for SCHED_OTHER.
Boinc (http://boinc.berkeley.edu/) client runs project processing jobs on
Linux using SCHED_BATCH scheduler policy and nice value 19. The nice value
is not displayable by ps.
Steps to Reproduce:
1. Run process using SCHED_BATCH scheduler policy with nice value.
./test-schedbatch 18 &
2. Display process details:
ps -o pid,ppid,user,comm,cls,nice
Results before:
[mike@rockover c]$ ps -o pid,ppid,user,comm,cls,nice
PID PPID USER COMMAND CLS NI
18205 2540 mike bash TS 0
20552 18205 mike test-schedbatch B -
20553 18205 mike ps TS 0
[mike@rockover c]$ awk '{printf "%5d %-17s %1d %2d\n", $1, $2, $41, $19}'
/proc/20552/stat
20552 (test-schedbatch) 3 18
Results after this patch:
[mike@rockover c]$ ps -o pid,ppid,user,comm,cls,nice
PID PPID USER COMMAND CLS NI
18205 2540 mike bash TS 0
20552 18205 mike test-schedbatch B 18
20553 18205 mike ps TS 0
Additional info: Here is the fragment from the sched_setscheduler(2) manual
page on the subject:
SCHED_BATCH: Scheduling batch processes
(Since Linux 2.6.16.) SCHED_BATCH can only be used at static
priority 0. This policy is similar to SCHED_OTHER in that it
schedules the process according to its dynamic priority (based on the
nice value). The difference is that this policy will cause the
scheduler to always assume that the process is CPU-intensive.
Consequently, the scheduler will apply a small scheduling penalty with
respect to wakeup behaviour, so that this process is mildly disfavored
in scheduling decisions.
This policy is useful for workloads that are noninteractive, but do
not want to lower their nice value, and for workloads that want a
determin- istic scheduling policy without interactivity causing extra
preemptions (between the workload's tasks).
