pwck, grpck - password/group file checkers

SYNOPSIS

/usr/sbin/pwck [ filename ] /usr/sbin/grpck [ filename ]

DESCRIPTION

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.
