getgrent() public

Returns an entry from the /etc/group file. The first time it is called it opens the file and returns the first entry; each successive call returns the next entry, or nil if the end of the file has been reached.

To close the file when processing is complete, call endgrent.

Each entry is returned as a Struct::Group:

  • Group#name contains the name of the group as a String.

  • Group#passwd contains the encrypted password as a String. An ‘x’ is returned if password access to the group is not available; an empty string is returned if no password is needed to obtain membership of the group.

  • Group#gid contains the group’s numeric ID as an integer.

  • Group#mem is an Array of Strings containing the short login names of the members of the group.
