NAME
chkgrp — check the syntax of the group file
SYNOPSIS
chkgrp [groupfile]
DESCRIPTION
The chkgrp utility scans the given file or, failing that, the system-wide group file for errors. 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.
FILES
/etc/group
group database file
SEE ALSO
DIAGNOSTICS
For each error found, chkgrp will print an error message containing the name of the file being scanned and the line number on which the error was found. Otherwise no output is produced.
The chkgrp utility returns EX_DATAERR if errors were found in the group file, and EX_OK otherwise.
HISTORY
The chkgrp utility appeared in FreeBSD 3.0.
AUTHORS
The chkgrp utility and this manual page were written by Dag-Erling Smørgrav <des [AT] FreeBSD.org>.
BUGS
Should check fields more thoroughly for allowed/disallowed characters, and the range of the group ID.
