Command to logout all the users in one command

Command to logout all the users in one command

It's only to logout all other user's except "root"


There are 2 alternatives - vote for the best!

Terminal - Alternatives
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.

who -u | grep -vE "^root " | kill `awk '{print $6}'`

skill -KILL -v /dev/pts/*

This command logs out all users - which is way more secure to use ps -ef and "grep" to kill processes.

Never ever use ps -ef piped to grep to kill something. If you ever need to ps-something use the UNIX95-directive, which makes sure you will never need "grep" together with "ps".

Know a better way?

If you can do better, submit your command here.

What others think

Add a `sort -u` so things will be killed only once:

who -u|grep -v root|awk {'print $6'}|sort -u|kill `awk {'print $0'}`

Or uniq

who -u|grep -v root|awk {'print $6'}|uniq|kill `awk {'print $0'}`
