.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.
It will also check for invalid characters in the group names
and group members.

utility returns

will print an error message containing the name of the file being
scanned and the line number on which the error was found.
