How to Kill user in Linux

Well if you want to kill a user’s process (in unix/linux hosting) or if you want to terminate a user’s process from the shell then you can use the following commands.

If you want the user jason’s process detailsps -aux |grep jason

from the output just kill the process id of that user and that user will be out from the shell without any wall message for him/her.

By other way you can do following.

Task: How to halt/stop user called jason

Type the skill command as follows:
# skill -STOP -u jason

You muse be root to stop other users.

Task: How to resume an already halted user called jason

To send a CONT signal to user jason, type the following command:
# skill -CONT -u jason

Task: How to kill and logout user called jason

To send a KILL signal, type the following command:
# skill -KILL -u jason

Task: Kill and logout all users

The ultimate command to kill and logout all users, type the following command:
# skill -KILL -v /dev/pts/*

Please note that you should send users a warning message or a logout notice using the wall command to avoid data loss.

Enjoy..
