Editing Ps (Unix) (section)

==Examples==
<syntaxhighlight lang="console">
# ps
  PID TTY          TIME CMD
 7431 pts/0    00:00:00 su
 7434 pts/0    00:00:00 bash
18585 pts/0    00:00:00 ps
</syntaxhighlight>

Users can [[Pipeline (Unix)|pipeline]] <code>ps</code> with other commands, such as [[Less (Unix)|less]] to view the process status output one page at a time:

<syntaxhighlight lang="console">
$ ps -A | less
</syntaxhighlight>

Users can also utilize the <code>ps</code> command in conjunction with the <code>[[grep]]</code>  command (see the <code>[[pgrep]]</code> and <code>[[pkill]]</code> commands) to find information about a single process, such as its id:<syntaxhighlight lang="console">
$ # Trying to find the PID of `firefox-bin` which is 2701
$ ps -A | grep firefox-bin
2701 ?        22:16:04 firefox-bin
</syntaxhighlight>

The use of <code>[[pgrep]]</code> simplifies the syntax and avoids potential race conditions:
<syntaxhighlight lang="console">
$ pgrep -l firefox-bin
2701 firefox-bin
</syntaxhighlight>

To see every process running as root in user format:
<syntaxhighlight lang="console">
# ps -U root -u
USER   PID  %CPU %MEM    VSZ   RSS TT  STAT STARTED        TIME COMMAND
root     1   0.0  0.0   9436   128  -  ILs  Sun00AM     0:00.12 /sbin/init --
</syntaxhighlight>
