This fragment lives in my ${HOME}/.env on pretty much every machine I log in to. If you
'export ENV=${HOME}/.env' in .profile, then configure sudo/doas to pass ENV
through unmolested, this will follow you as you switch uids.
_hostname=$(hostname | sed -e 's/\.hushmail\(inc\)*\.com$//')
awd=$(which awd 2>/dev/null)
if [ "${awd}" == "" ] ; then
awd=':'
fi
setprompt () { PS1=": $(id -un)@$_hostname:$(pwd); " ; }
cd () { command cd "$@" && setprompt && ${awd} ; }
setprompt
It works with pretty much every Bourne/Korn shell variant I've stumbled across.
Adjust the _hostname bit to match the domains of the systems you regularly log in to, and
drop the awd bits if you don't use plan9port.
