PWD_UNMKDB(8)		    System Manager's Manual		 PWD_UNMKDB(8)

NAME
       pwd_unmkdb -- build plain-text password file from database

SYNOPSIS
       pwd_unmkdb [-i db-file] [-o out-file]

DESCRIPTION
       The  pwd_unmkdb	utility	 reads	through	 a db(3) style secure password
       database	generated by pwd_mkdb(8).  It uses this	info to	 generate  the
       plaintext master.passwd(5) style	file that was used to create it.

       By  default,  it	 reads	the file spwd.db in the	current	directory, and
       outputs into master.passwd, also	in the current directory.

       The options are as follows:

       -i db-file
	     Use the specified db file as the source, instead of  the  default
	     spwd.db.

       -o out-file
	     Output   into   the   specified  file,  instead  of  the  default
	     master.passwd.

       A simple, tool, to be sure.  However, it's extremely useful if you lose
       or corrupt /etc/master.passwd somehow.  I know I've done	it a few times
       by fat-fingering	in vipw(8), and	it's surprisingly common  to  b0rk  it
       when  using  mergemaster(8).   You can recover from backups the nightly
       runs make, but you lose changes since then.  Using pwd_unmkdb lets  you
       get exactly what	the system is using, in	a format you can work with.

       The pwd_unmkdb utility exits zero on success, non-zero on failure.

FILES
       spwd.db	      The  default  secure  password database file used	as the
		      source.
       master.passwd  The default flat-text password file the info  is	output
		      into.
