chkgrp(8)

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. It will also check for invalid characters in the

group names
and group members.

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.

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.
