Issue
I would like to kill a list of PID that correlates to a process in a tcsh shell. I ran the following command:
> losf <file> | awk '{print($2)"'
The command will show a list of PIDs.
pid1
pid2
...
I then ran the following command to kill those PIDs.
> kill -9 `lsof <file> | awk'{print($2)}'`
When the kill command is executed, the terminal just somehow hanged without killing any PID. I then had to revert to killing those PID one by one.
Therefore, is there a way to do what I intended to do as illustrated above? Thank you.
Solution
xargs is a standard utility for performing action on each given line read from standard input. You could use it like this:
> lsof <file> | awk '{print($2)}' | xargs -I '{}' kill {}
