How can I tell, from a Korn shell script, if the script is running in a vi sub-shell?
I have a script that has a problem when run from a vi subshell, and I'd like to check for that condition and just issue an error message.
(I know that's not the solution to the problem, but the thing that fails is being replaced, so this is a temporary "fix")
Thank you
