Command to logout all the users in one command

who -u | grep -vE "^root " | kill `awk '{print $7}'`
Logs all users out except root. I changed the grep to use a regexp in case a user's username contained the word root.

What Others Think

Hi Professortux, I have used the command given by you, but it doesn't work because you have awk the field 7 which specifies the IP address of the login. I have changed the command as follows, and it works fine. who -u | grep -vE "^root " | kill `awk '{print $6}'`

Life is a journey, you don’t care about the destination, you care about the scenery along the way and the mood of seeing the scenery. Others laughed at me as crazy, I laughed at others and couldn't see through.
