NAME

  pwck,	grpck -	Checks the password and	group files for	inconsistencies

SYNOPSIS

  pwck [-admNs]	[file]

  grpck	[-mNp] [file]

OPTIONS

  -N  Causes both pwck and grpck to additionally check the NIS database
      entries using the	same consistency tests.	Users that are defined in the
      local password or	group file without the "+" at the start	of the name
      field are	optionged as duplicate entries.

  pwck


  -a  Inhibits the running of the /tcb/bin/authck -p command on	a system run-
      ning Enhanced Security.

  -d  Prevents pwck from checking for the presence of the user's login direc-
      tory.

  -m  Directs pwck to check for	mixed case usernames.

  -s  Causes pwck to check for the presence of the optional shell field	for
      each entry.

  grpck


  -m  If there are no members, causes grpck to display a message indicating
      the listed group has no members.

  -p  Directs grpck to not check for a users' existence	in the password	data-
      base (local or NIS).

DESCRIPTION

  The pwck command scans the /etc/passwd file, or the named file, and writes
  to standard out any inconsistencies.	The scan checks	the number of fields,
  login	name, user ID, group ID, and existence of a login directory and
  optional program name.

  The grpck command scans the /etc/group file, or the named file, and writes
  to standard out any inconsistencies.	The scan checks	the number of fields,
  group	name, group ID,	and whether all	login names appear in the password
  file.



EXAMPLES

  To verify the	password information in	the /etc/passwd	file for consistency,
  enter:

       pwck

  To verify the	password information in	the /etc/passwd	file and the NIS
  database for consistency without checking each users login directory vali-
  dity,	enter:

       pwck -Nd

  To verify the	group information in the /etc/group file and the NIS database
  for consistency, enter:
