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

SYNOPSIS
       pwck [-admNs] [file]

       grpck [-mNp] [file]

OPTIONS
       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
       Inhibits the running of the /tcb/bin/authck -p command on a system run‐
       ning  Enhanced  Security.  Prevents pwck from checking for the presence
       of the user's login directory.  Directs pwck to check  for  mixed  case
       usernames.  Causes pwck to check for the presence of the optional shell
       field for each entry.

   grpck
       If there are no members, causes grpck to display a  message  indicating
       the  listed  group  has	no  members.  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  consis‐
       tency, 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

FILES

       information Contains group information
