Specifically, it checks that every non-blank, non- comment entry is composed of four colon-separated fields, that none of them contains whitespace, and that the third field (the group ID) is numeric. It will also check for invalid characters in the group names and group mem- bers. The following options are available: -q This option disables printing of text when the group format is cor- rect. FILES /etc/group group database file EXIT STATUS The chkgrp utility returns EX_DATAERR if errors were found in the group file, and EX_OK otherwise.
