NAME    [Toc]    [Back]

     pwck - password file checker

SYNOPSIS    [Toc]    [Back]

     pwck [[-p]	file]

DESCRIPTION    [Toc]    [Back]

     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.

     pwck has the ability to parse YP entries in the password file.

     The -p option prevents checking of	the login directory and	shell fields,
     useful for	NIS administrators in checking the yppasswd file, where	each
     login directory is	not usually locally available.

FILES    [Toc]    [Back]

     /etc/passwd

SEE ALSO    [Toc]    [Back]

     passwd(4).
