pwck(8)
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
      running Enhanced Security.

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

  -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
      database (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
  validity, enter:

       pwck -Nd

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

       grpck -N
