Polecenie ps

Include only specified processes, which are given in a space-delimited list.

Include only specified session IDs, which are given in a space-delimited list.

As a, list all processes on a terminal. As -a, list all processes except session leaders and processes not associated with a terminal.

As -c, show different scheduler information with -l. As c, show the true command name.

Select by command name.

Set the output width (the number of columns to display).

Select all processes except session leaders.

Select all processes.

Include environment information after the command.

As -f, display full listing. As f or --forest, display "forest" family tree format, with ASCII art showing the relationships.

Set extra-full format; implies -f.

For -g, select by session leader if list contains numbers, or by group if it contains group names. For -G, select by the group IDs in list. --group selects by effective group and --Group selects by real group, where groups can be either group names or group IDs.

Suppress header. If you select a BSD personality by setting the environment variable PS_PERSONALITY to bsd, then h prints a header on each page.

Display "forest" family tree format, but without ASCII art.

Display threads as if they were processes.

Repeat headers on every output page.

Display help information and exit.

Print debugging information.

Jobs format. j prints more information than -j.

Specify sort order. Syntax for the specification is:

[+|-] key[,[+|-] key...] ]

The default direction is +, for increasing numerical or alphabetic order. See Format and sort specifiers for possible keys.

Produce a long listing. -l prints more information than l and is often used with -y.

Print list of field specifiers that can be used for output formatting or for sorting.

Show threads, possibly with LWP and NLWP columns.

Set the screen height to num lines. If --headers is also set, the headers repeat every num lines.

Show threads after processes.

Print user IDs and WCHAN numerically.

Specify the System.map file for ps to use as a namelist file. The map file must correspond to the Linux kernel—e.g., /boot/System.map-2.4.19.

Negate the selection, selecting all processes that do not meet the specified conditions.

As -o, o, or --format, specify user-defined format with a list of fields to display.

As -O, this option is like -o, but some common fields are predefined. As O, this option can be either the same as -O in specifying fields to display, or can specify single-letter fields for sorting. For sorting, each field specified as a key can optionally have a leading + (return to default sort direction on key) or - (reverse the default direction).

Select by parent process IDs.

Show only processes that are currently running.

Display signal format.

Include some dead child process data in parent total.

Display processes running on the specified terminals. t with no terminal list displays processes for the terminal associated with ps. Specify - to select processes not associated with any terminal.

Display all processes on this terminal. Like t with no argument.

Display threads, possibly with SPID column,

As u with no argument, display user-oriented output. As -u or --user, display by effective user ID (and also support names), showing results for users. With no argument, -u displays results for the current user.

As U, display processes by effective user ID. As -U or --User, display processes for users by real user ID (and also support names).

Display virtual memory format.

Display version information and then exit.

Wide format. Don't truncate long lines. Use twice to set an unlimited width.

Set screen width.

Display processes without an associated terminal.

Use old Linux i386 register format.

Do not show flags; show rss instead of addr. Requires -l.
