Unhappy


This is actually not just for Linux; I'm searching for a POSIX-compliant solution. I'm trying to set up a perl (and perhaps csh) script to temporarily switch the user's group to one of it's supplementary groups, "do it's thing", then switch back to it's primary group once the script has finished. The results I've had with the newgrp command are less than elegant. It seems as though I'm still stuck with the supplementary group assignation after the script ends. Adding another newgrp command at the end of the script to set it back to the primary just adds another shell layer. Putting "exit" or "logout" at the end of the script does nothing although typing "exit" on the command line after the script has completed sets it back to the way I want it. Any guidance would be appreciated.

Have you tried sg? It sounds like it may not meet your requirements though. Not csh.

This is from the newgrp man page:

Quote:
The sg command works similiar to newgrp but does not
replace the user's shell, so upon exit from a sg command,
you are returned to your previous group ID. sg also
accepts a command. The command will be executed with the
Bourne shell and must be enclosed in quotes.
