Suspend process without killing it

killprocess

So I've got a persistent program running in the background. Killing it just causes it to restart with a different PID. I'd like to suspend it (put it to sleep without actually killing it). Does kill -9 do this? If not, how should this be done?

Best Answer

kill -STOP $PID
[...]
kill -CONT $PID

@jordanm adds: Also note that like SIGKILL (kill -9), SIGSTOP can not be ignored.

XkbOptions refers to a rule defined in the XKB rules file, normally /usr/share/X11/xkb/rules/base, which will look like:

terminate:ctrl_alt_bksp =   +terminate(ctrl_alt_bksp)

That in turn picks up the definition from the terminate symbols file, normally /usr/share/X11/xkb/symbols/terminate. I'm not sure if you can just add more modifiers to the type="CTRL+ALT" line there or if there's limits on the type value.

Documentation on XKB customization can be found at http://www.x.org/wiki/XKB and may be able to help fill in some of the gaps in this answer.

Linux Kill Command – Kill Process Based on Arguments

pgrep/pkill take a -f flag. From the man page:

-f    The pattern is normally only matched against the process name.
      When -f is set, the full command line is used.

For example:

$ sleep 30& sleep 60&
[1] 8007
[2] 8008

$ pkill -f 'sleep 30'
[1]  - terminated  sleep 30

$ pgrep sleep
8008
