sudo kill -9 $( pgrep sshd )
sshd is the command to kill, easier then the old post
old post
Simply open Your terminal ctrl+alt+T an type
fem@ordinateur:~$ ps -ef | grep ingularity | awk '{print$2}' | xargs kill -9
Let's analyze the code....
fem@ordinateur:~$ ps -ef | grep ingularity
give the output of current processes filtering them with the "ingularity" string.
fem@ordinateur:~$ ps -ef | grep ingularity | awk '{print$2}'
Then pipe the output to awk that extract the pid and print them (the second column only).
fem@ordinateur:~$ ps -ef | grep ingularity | awk '{print$2}' | xargs kill -9
Then pipe again sending to xargs and kill to terminate the pid found
Bye
