Either I am not able to phrase my search correctly or the answer is not easy to find!, but I am trying to figure out how to list all of my background task PIDs. For example:
So far I have found that to list the last PID we use:
$!
But now I want to list the PID of the task before that (if one exists), but I can't find how to do that. Utlimatly I want to list all my background task PIDs.
I know we can also find last job ID with:
%% (last job in list)
%1 (first job in list)
%2 (second job in list)
But the same does not seem to work for process id?
Thanks all :)
Use ps S
. For example:
$ vim &
[1] 8263
$ ipython &
[2] 8264
$ ps S
PID TTY STAT TIME COMMAND
3082 pts/0 Ss 0:00 bash
3137 pts/0 Sl+ 0:00 python /usr/bin/ipython
8207 pts/2 Ss 0:00 bash
8263 pts/2 T 0:00 vim
8264 pts/2 Tl 0:00 python /usr/bin/ipython
8284 pts/2 Tl 0:00 python /usr/bin/ipython
8355 pts/2 R+ 0:00 ps S
If you want get PIDs use below:
$ ps S | awk '{print $ 1 }' | grep -E '[0-9]'
3082
3137
8207
8263
8264
8284
8357
8358
835
Also you can use jobs -l
But it show background processes only for current session.
