Well, to split a hair, much like we are used to doing with the RM...
While the above works most places, I do not believe it is ensured to be
portable on a POSIX compliant system. If you want to stay within POSIX then
it is not possible. That is, "csh" is not required for a POSIX compliant
CAVEAT: I don't have the latest POSIX documents, so perhaps "csh" or "tcsh"
have been added.
