I tried something yesterday related to a discussion of the MKS shell (MS DOS),
where someone wanted a ".logout" equivalent for the Korn shell.

In /etc/profile I put the following line:

	trap ". $HOME/.logout" 0 1 3

and in $HOME/.logout any commands that I want executed every time I log out.

This works on my Microport System V machine.

Actually, the trap line in /etc/profile is within a case statement which 
checks for a $0 of "-sh" - since we don't want this to execute whenever we
leave ANY old shell, but only when we leave the login shell.

Putting whatever you want to happen on logout into a separate shell script
removes all of the ambiguities and pitfalls of when it will be interpreted
by the shell - it won't, until the trap is sprung and the separate shell
script is read.
