     grpck - group file	checker

     /usr/sbin/grpck [file]

     grpck verifies all	entries	in the group file. This	verification includes
     a check of: the number of fields, group name, group ID, whether all login
     names appear in the password file,	duplicate logname entries, and maximum
     number of groups per logname. The default group file is /etc/group.

     grpck has the ability to parse YP entries in the group file.
