Returns an array containing the elements of the password structure. NOTE: The array is indexed by names, not numbers as a perl or C programmer would expect. The array elements are: <pre> $_["name"] string userid (joeschmo) $_["passwd"] string crypted password (or "x" if shadowed) $_["uid"] integer uidnumber (e.g. 0 for root) $_["gid"] integer primary gidnumber (e.g. 0 for wheel/root) $_["gecos"] string name (Joseph P. Schmoe) $_["dir"] string home directory (/home/joeschmo) $_["shell"] string loginshell (/bin/slash) </pre> nikolai-zujev-
