grpck


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 verifica-
     tion  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.
