how can execute some commands when a user logs out
 

hi, i want to execute a set of commands when a user logs out.how can i do that?
thanks

Maybe with edit a .bash_logout in the user directory

[ edit ]
...but only works if the user shell is bash I don't know the procedure for other shell

csh is ~/.logout , just read the man page for w/e shell u r using and search for logout.
