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

This means that the login names may be supplied by a network name service. SunOS 5.10 20 Oct 2002 pwck(1M)
