executing script as secondary group

[philipose]

Hi,
I have a user id myid on an AIX 5.3 server with primary group group1 and secondary group group2. I want to execute a shell script script1 as if I am executing by an id with a user id in primary group group2.

If I have to execute script1 from the shell, i can execute the command
newgrp - group2
and run
sh script1
to get the desired results

But if script1 was called from another script, say callscript, I was not able to put the below 2 lines in callscript and get the same results

newgrp - group2
sh script1

Any ideas ??
Thanks

The man page of newgrp says that:

Note: The newgrp command does not take input from standard input and cannot be run from within a script.

Any idea how I can do the equivalent via a script ?

Thanks

I think I can do this by setting the gid on the callscript and assigning the desired group ownership to callscript. Let me give that a try

You'll need a c-program wrapper around the script. Shell scripts don't follow suid/sgid bit settings like real executables do.

sudo perhaps?

Bummer. I dont have sudo rights and prefer to keep this within shell scripts. I am hoping a better soln will prevail.
