Re: test -t can distinguish compile sessions

[Robert Hundt]

Hey Dan,

I guess you would have to check the process tree (via ps -ef) and see
whether emacs is somwhere the parent of your current shell.

For example (on HP-UX, needs adjustment for your shell):

ps -ef | grep `ps -ef | grep $$ | grep ksh | grep -v grep | awk '{ print
$3 }' ` >out
cat out | grep -v /ksh | grep -v grep | grep /emacs
if [[ $? = 0 ]] then
   echo "We are emacs"
fi
