Hi,
Thanks for the suggestion.
There are some tasks which are directly tied to the group-id. Owing to
the requirement it may happen my perl script need to switch groups to
achieve a specific task. So my plan is to change to a new group with new
grp command after exporting the Environment/required variables from the
current shell.
After the newgrp system command from a perl script could not satisfy my
need I tried including the command in a separate .cshrc file and then
just sourcing that file from a perl script. But this job could not again
be executed from perl script . The perl script returns error telling the
sourced file could not be found.
Moreover changing the scripts group permission wont do hold good for my
case.
I am at bay now !!
Regards,
Suvajit

Hi,
I want to login into a new group using 'newgrp' UNIX command.Every
newgrp command invokes a new shell.
But when I am trying to execute this system command from a perl
script the script is terminating and returning the prompt of the new
shell .
Can anyone suggest on what can be done to change into a new group
from within perl script?
Short answer: You can't.
Long answer:
The newgrp command will always run a new shell regardless if it
succeeds or fails. What you can do instead is set the effective group
id for the script.
1. Change the script's group to the group you want it to work under
(see `man chgrp`).
2. Change the script's "set group id on execution" flag (see `chmod`).
The script will now run under the new group.
See `perldoc perlvar` and search for $) and $(.
