(CCing the Screen users list, in case anybody else is interested in this, too.)

I've attached a copy of the script I'm currently using to auto-join Screen when I start a shell. I call it 'Porch'. Here's a pretty comprehensive feature list: * All new BASH instances will join the same screen session. If it doesn't exist, the first shell will start it, and then join. * All shells join the session co-operatively (the '-m' flag), so that each new joiner doesn't kick the rest off. * Auto-exits the shell when Screen terminates, or when the display detaches. * Allows a short timeout, with a PRESS ANY KEY TO CANCEL type message displayed, for the user to cancel joining the session or exiting the shell when the session terminates/detaches. * If you manually cancel out of joining a Screen session, it remembers, and exports a flag to sub-shells that supresses the auto-joining behavior. * Ignores non-interactive shells. * Ignores already-'Screened' shells. (With an exception, see below.) * Inserts the Screen session name into your "hardstatus" line, automatically, by modifying BASH's $PROMPT_COMMAND. (This normally isn't possible because Screen's own 'hardstatus string ...' command doesn't support an escape for the session name.) There are some broken bits that I haven't had time to finish debugging, though. I'm trying to make it nest properly, so that you can join a local Screen session, and then run an SSH client from within the local session that connects to a remote host, and then join a remote Screen session. (This requires installing the script on both the local and remote hosts, of course.) But for now, it works well enough to be useful. I never have to regret not starting a Screen session, earlier. I'm making this available as-is, in case anyone wants to use it, copy it, or just get ideas from it. I would appreciate any suggestions, feedback, or patches, too. To use it, save a copy locally (I stick it in '/usr/bin'), and source it at the end of your .bashrc, like this: . /usrbin/porch.sh -Ryan
porch.sh
