How many ways do you know that one can use to log out from a Linux/UNIX bash shell ?

Please, be aware that some of the commands are DANGEROUS if you're logged in as ROOT because they may and will stop services/daemons that usually run as ROOT.

Here are at least 7 commands that you may use to log out.

1. logout
2. exit
3. CTRL+D
4. export TMOUT=1
5. fuser -k `pwd` ( Don't do this as ROOT!!! )
6. skill -KILL -u `whoami` ( Don't do this as ROOT!!! )
7. kill -9 $$ ( Don't do this as ROOT!!! )
   

TMOUT - turns on autologout feature and if there is inactivity for NNN seconds the user is logged out from the shell.
