How to find PID of an ongoing job in UNIX?

Question

I executed a shell script which will call some internal applications and will take few hours. Due to some problems, I have to stop or kill that job. For this, first of all, I ran ps -u $uname to list all the ongoing jobs.

PID TTY         TIME CMD
 14172 pts/1       0:00 ps
 12939 ?           0:00 sshd
 12904 ?           0:01 sshd
 13132 pts/1       0:00 bash
 12945 pts/1       0:00 sh
 12897 ?           0:00 sshd

Now, how will I find correct PID to kill?

Solution 1

you can also consider do use

pgrep "you_script"

or

pgrep -f "complete_cmd_line_of_script"

"process-grep" results only the PID

If you want to kill the process you found, you also can use pkill, which uses the same syntax as pgrep

Solution 2

ps aux | grep "your_script_name.sh"

If you add the option -f (full) you get more details about the command (CMD). With that information you may be able to do a grep.

What is the wrong with this question which tends people to downvote?

you should pipe grep, grep and awk ! If yourscript is a fixed string 1) use | grep [y]ourscript (this avoid a |grep -v grep), 2) then for awk, use ps aux | awk '/[y]ourscrip/ { print $2} '
