.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
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.
|
|

|
if errors were found in the group file,

|
and

.Dv EX_OK
|
|
otherwise.
|
|
.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.
