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 $(.
