Re: Want to Create Unix group using perl script

in reply to Want to Create Unix group using perl script

For checking if a group exists you can use getgrnam (scalar getgrnam("foo") — returns the GID, or undef if a group of the given name doesn't exist).

For creating a new group, I'd use the respective command supplied by your system, such as groupadd (call it via system) — there's no reason to reinvent the wheel and run into various gotchas that can be avoided by using existing tools.

It seems groupadd already does everything the OP wants: if the group doesn't exist, it adds it - if it does exist, it prints a message it already exists.

Looks to me the OP just wants a three line shell script. Doesn't seem worth the trouble of writing a Perl wrapper for that.
