>> Shell Tip: How to execute a script for each logout
-----------------------------------------------------------------

Sometimes it's useful to execute a command after each
logout, i.e. to cleanup temporary directories, or to log
working hours.

This is the way to make the shell execute the script
$HOME/.logout after each logout:

1. Insert this line at the beginning of the file
$HOME/.profile:

trap ". $HOME/.logout" 0

2. Create a file named "$HOME/.logout", that may contain
arbitrary shell commands, i.e.

$ cat > $HOME/.logout
echo "Good bye $LOGNAME, the time is `date`"
^D

That's it! After the next login, the shell will execute
the contents of the file "$HOME/.logout".

NOTE: this will not work for C-Shell dialects, i.e. TCSH



Of course, you will need to set the .logout script so that it looks for and umounts (if found) any flash drives.
