3.2.44 getgrent

getgrent setgrent endgrent

These functions do the same thing as their like-named system library routines - see getgrent (3). These routines iterate through your /etc/group file (or its moral equivalent coming from some server somewhere). The return value from getgrent in list context is:

($name, $passwd, $gid, $members)

where $members contains a space-separated list of the login names of the members of the group. To set up a hash for translating group names to gids, say this:

while (($name, $passwd, $gid) = getgrent) {     $gid{$name} = $gid; }

In scalar context, getgrent returns only the group name.
