grpck(1M)               (BSD Compatibility Package)               grpck(1M)


   NAME
         grpck - check group database entries

   SYNOPSIS
         /usr/ucb/grpck [ filename ]

   DESCRIPTION
         grpck checks that a file in group(4) does not contain any errors; it
         checks the /etc/group file by default.

         This command differs from /usr/sbin/grpck in its ability to correctly
         parse YP entries in /etc/passwd.

   FILES
         /etc/group

   SEE ALSO
         group(4), passwd(4) in the System Administrator's Reference Manual.

   DIAGNOSTICS
         Too many/few fields
               An entry in the group file does not have the proper number of
               fields.

         Bad character(s) in group name
               The group name in an entry contains characters other than
               lower-case letters and digits.

         Invalid GID
               The group ID field in an entry is not numeric or is greater
               than 65535.

         Null login name
               A login name in the list of login names in an entry is null.

         Login name not found in password file
               A login name in the list of login names in an entry is not in
               the password file.
