.Sh DESCRIPTION
The

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.
.Sh FILES
.Bl -tag -width /etc/group -compact
.It Pa /etc/group
group database file
.El
.Sh SEE ALSO
.Xr getgrent 3 ,
.Xr group 5
.Sh DIAGNOSTICS
For each error found,
.Nm
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.
.Pp
The
.Nm
utility returns
.Dv EX_DATAERR
if errors were found in the group file,
and
.Dv EX_OK
otherwise.
.Sh HISTORY
The
.Nm
utility appeared in
.Fx 3.0 .
.Sh AUTHORS
The
.Nm
utility and this manual page were written by
.An Dag-Erling Co\(:idan Sm\(/orgrav Aq des@FreeBSD.org .

characters, and the range of the group ID.
