NAME

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

SYNOPSIS

       pwck [-admNs] [file]

       grpck [-mNp] [file]

FLAGS

       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 flagged as duplicate entries.

   pwck
       Inhibits the running of the /tcb/bin/authck -p command on a system running 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.

   grck
       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 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

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. The default group file is
       /etc/group.

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

FILES

       /etc/group

       /etc/passwd

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.
