NAME

mkpasswd − Creates a version of the basic user database organized for efficient searches

SYNOPSIS

/usr/sbin/mkpasswd −v passwdfile

DESCRIPTION

The mkpasswd command creates an auxiliary version of the basic user database in a form organized for efficient searches by the getpwuid subroutine and the getpwnam subroutine.  The mkpasswd command reads the user attributes in the /etc/passwd file and creates a hashed password database in the /etc/passwd.dir and /etc/passwd.pag files (see ndbm(3) reference page). 

If you specify a file other than /etc/password, the command reads the user attributes in that file and creates a hashed password database in the passwdfile.dir and passwdfile.pag files. It is important to know that the password file you designate be in password file format (see the passwd(4) reference page.) 

Only the root user should have execute access to this command.

EXAMPLES

If you have not used vipw to edit the /etc/passwd and wish to generate a hashed password database, enter the following:

mkpasswd −v /etc/passwd

An auxiliary version of the basic user database (/etc/passwd.dir and /etc/passwd.pag files) is created with a hashing algorithm.
