NAME

pwck, grpck − password/group file checkers

SYNOPSIS

/etc/pwck [file]
/etc/grpck [file]

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 optional program name exist.  The criteria for determining a valid login name are taken from HP-UX System Administrator Manual for your system.  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, and whether all login names appear in the password file. The default group file is /etc/group. 

DIAGNOSTICS

Group entries in /etc/group with no login names are flagged.
