NAME
       pwck, grpck - password/group file checkers

SYNOPSIS
       /usr/sbin/pwck [filename]

       /usr/sbin/grpck [filename]

DESCRIPTION
       pwck  scans the password file and notes any inconsistencies. The checks
       include validation of the number of fields, login name, user ID,	 group
       ID,  and	 whether  the  login directory and the program-to-use-as-shell
       exist.  The default password file is /etc/passwd.

       grpck  verifies all  entries  in	 the  group  file.  This  verification
       includes a check of the number of fields, group name, group ID, whether
       any login names belong to more than NGROUPS_MAX groups,	and  that  all
       login names appear in the password file. grpck also issues a warning if
       it finds an entry (a single line) in the group file longer  than	  2047
       characters.   Such  an entry causes group maintenance commands, such as
       groupdel(1M) and groupmod(1M), to fail.

       The default group file is /etc/group.

       All messages regarding inconsistent entries are placed  on  the	stderr
       stream.

FILES
	   o	  /etc/group

	   o	  /etc/passwd

SEE ALSO
       groupdel(1M),	groupmod(1M),	getpwent(3C),	group(4),   passwd(4),
       attributes(5)

DIAGNOSTICS
       Group entries in /etc/group with no login names are flagged.

       Group file 'filename' is empty

	   The /etc/passwd or /etc/group file is an empty file.

       cannot open file filename: No such file or directory

	   The /etc/passwd or /etc/group file does not exist.

NOTES
       If no filename argument is given,  grpck checks the local  group	 file,
       /etc/group, and also makes sure that all login names encountered in the
       checked group file are known to the system  getpwent(3C) routine.  This
       means that the login names may be supplied by a network name service.
