DESCRIPTION

ps prints information about selected processes. Use options to specify which processes to select and what

information to print about them.

Refer to usergroupname(5) to understand the functionality changes with the Numeric User Group Name

feature.

Process Selection Options

Use the following options to choose which processes should be selected.

Note: If an option is used in both the default (standard HP-UX) and UNIX Standard (see standards (5))

environments, the description provided here documents the default behavior. Refer to the Notes section

for additional information on UNIX Standard behavior.

(none) Select those processes associated with the current terminal.

-A (UNIX Standard Only, see standards (5)) Select all processes. (Synonym for -e.)

-a Select all processes except process group leaders and processes not associated with

aterminal.

-C cmdlist (UNIX Standard Only, see standards (5)) Select processes executing a command

with a basename given in cmdlist .

-d Select all processes except process group leaders.

-e Select all processes.

-g grplist Select processes whose process group leaders are given in grplist .

-G gidlist (UNIX Standard Only, see standards (5)) Select processes whose effective group ID

numbers or group names are given in gidlist . (see usergroupname(5)).

-n namelist (UNIX Standard Only, see standards (5)) This option is ignored; its presence is

allowed for standards compliance.

-p proclist Select processes whose process ID numbers are given in proclist .

-R prmgrplist Select processes belonging to PRM process resource groups whose names or ID

numbers are given in prmgrplist . See DEPENDENCIES.

-s sidlist (UNIX Standard Only, see standards (5)) Select processes whose session leaders are

given in sidlist . (Synonym for -g).

-t termlist Select processes associated with the terminals given in termlist .Terminal

identiﬁers can be speciﬁed in one of two forms: the device’s ﬁle name (such as

tty04) or if the device’s ﬁle name starts with tty, just the rest of it (such as 04).

If the device’s ﬁle is in a directory other than /dev or /dev/pty, the terminal

identiﬁer must include the name of the directory under /dev that contains the dev-

ice ﬁle (such as pts/5).

-u uidlist Select processes whose real user ID numbers or login names are given in uidlist .

(see usergroupname(5)).

-U uidlist (UNIX Standard Only, see standards (5)) Select processes whose real user ID

numbers or login names are given in uidlist . (see usergroupname(5)).

-Z pset_list Select processes whose processor set ID’s are given in pset_list . This option is sup-

ported only if the kernel supports processor sets functionality.

PAGE 2
ps(1) ps(1) If any of the -a, -A, -d, or -e options is specified, the -C, -g, -G, -p, -R, -t, -u, -Z, and -U options are ignored. If more than one of -a, -A, -d, and -e are specified, the least restrictive option takes effect. If more than one of the -C, -g, -G, -p, -R, -t, -u, -Z, and -U options are specified, processes will be selected if they match any of the options specified.
PAGE 3
ps(1) ps(1) COMMAND if -o is specified and CMD otherwise. cls Process scheduling class, see rtsched (1). comm The command name. The output in this column may contain spaces. The default heading for this column is COMMAND if -o is specified and CMD otherwise. cpu Processor utilization for scheduling. The default heading for this column is C. etime Elapsed time of the process. The default heading for this column is ELAPSED.
PAGE 4
ps(1) ps(1) Z T X Terminated Stopped Growing The default heading for this column is S. stime Starting time of the process. If the elapsed time is greater than 24 hours, the starting date is displayed instead. sz The size in physical pages of the core image of the process, including text, data, and stack space. Physical page size is defined by _SC_PAGE_SIZE in the header file (see sysconf (2) and unistd (5)). time The cumulative execution time for the process.
PAGE 5
ps(1) ps(1) International Code Set Support Single-byte character code sets are supported. EXAMPLES Generate a full listing of all processes currently running on your machine: ps -ef To see if a certain process exists on the machine, such as the cron clock daemon, check the far right column for the command name, cron, or try ps -f -C cron WARNINGS Processes can change while ps is running. The ps command displays processes at only a snapshot in time. Data printed for defunct processes is irrelevant.
