Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Kill a process by application

Terminal - Kill a process by application
kill -9 `pgrep $PROCESS_NAME`

Kill a process by application

The pgrep retrieves the PID, then the KILL receive it, and kill it...

It works also if the application has more than one instance....


There is 1 alternative - vote for the best!

Terminal - Alternatives

voted down for the use of backticks. behold, the way of the Jedi:

kill -9 P(pgrep $PROCESS_NAME)

and i give up. if only you could edit comments

Comment by atoponce 357 weeks and 4 days ago

atoponce: I don't think that's a good reason to vote this command down. By using backticks in the example, it also applies shells which do not support the newer style syntax. This isn't a bash or zsh only website. When available... sure, $() is a good habit... it makes complex substitutions much easier. But in this instance, there is no benefit to using one over the other.

How about this. The same package that installs pgrep on most (all) distributions also installs pkill.

pkill -x $PROCESS_NAME pkill -9 -x $PROCESS_NAME

Note: Don't worry atoponce, I've got your back.
