Why is this a problem? If I'm not logged in, why does this shell setup code need to be invoked. Makes perfect sense to me that it is only invoked on login.

What do you see that "suggests" this? The shells are being properly logged out: [04:39:21][r...@greer]/$ ps PID TTY TIME CMD 25938 pts/0 00:00:00 su 25939 pts/0 00:00:00 bash 25949 pts/0 00:00:00 ps [04:39:34][r...@greer]/$ exit exit [04:39:42][s...@greer]~$ ps PID TTY TIME CMD 25867 pts/0 00:00:00 bash 25951 pts/0 00:00:00 ps And when I exit su, the prompt colors properly change back to the stan user. Believe me, of all people, if processes were left hanging around, _*I*_ would be the first to notice and fix ir. I run Samba from inet to cut down on needless processes for Pete's sake. ;) I'm a process efficiency freak. As a matter of fact I've been trying to figure out the last couple of days how to get my dovecot-auth process count back down to 1 since upgrading to the Dovecot 1.2.10 backport. For some reason it just doesn't want to run with less than 2 auth processes. I only need one. I'll get it figured out soon. > What you really want to do is execute some code as root on > logout. Why? It works perfectly. Well, except for an unrelated command line wrap issue, but I'll work that out as soon as it bugs me enough. It applies to both user shells, something in my PS1 export probably as I don't recall the issue before those changes to the PS1s. > One hacky way to do it is to call reset in root's > logout script: > > $ sudo su - > root promptr...@~# cat .bash_login > export PS1='root prompt\[\033[0;31...@\w\$\033[0;30m \]' > root promptr...@~# cat .bash_logout > reset > root promptr...@~# > <screen clears> > $ > > This is a bit slow, mind, if you really want to change the > text colour for the root user then you should "unwind" the > control characters instead by preserving the older PS1 and > keeping track of which control sequences you've "opened": > > ~root/.bash_login: > export OLDPS1="$PS1" > export PS1="whatever you want" > ~root/.bash_logout: > echo "control chars that reset the text colours" > export PS1="$OLDPS1" Again, why would I want to do this when the coloring etc works properly already when switching into and out of su? I must be missing something in your madness. ;) -- Stan -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
