Automating 'newgrp' command - how?
Hi,

I have to add the 'newgrp' command to my login (.cshrc) script.

The problem is that if I add it, it comes to infinite look, since newgrp opens new shell again and again.

How to automate the newgrp when I have to login, and avoid that loop?

Currently I'm thinking of a condition that creates temporary file and run the newgrp if that file exists (one time only). Do you have a better idea?

Thanks in advance

Cannot test it right now, but did you try something like this:

Code:
exec newgrp ...

Hi.

exec seems to make matters worse.

Try putting the call to newgrp in your $HOME/.login script. .login only gets executed once at login.

If you need to run newgrp with the - (or -l) flag then your idea of a temporary file might be better
