#!/usr/bin/perl

while(($name, $passwd, $uid, $gid, $quota,
   $comment, $gcos, $dir, $shell)=getpwent()) {
   print "Name=$name\n";
   print "Password=$passwd\n";
   print "UID=$uid\n";
   print "GID=$gid\n";
   print "Quota=$quota\n";
   print "Comment=$comment\n";
   print "Gcos=$gcos\n";
   print "HOME DIR=$dir\n";
   print "Shell=$shell\n";
}

setpwent() ; # Rewind the databse /etc/passwd

while(($name, $passwd, $uid, $gid, $quota,
   $comment, $gcos, $dir, $shell)=getpwent()) {
   print "Name=$name\n";
   print "Password=$passwd\n";
   print "UID=$uid\n";
   print "GID=$gid\n";
   print "Quota=$quota\n";
   print "Comment=$comment\n";
   print "Gcos=$gcos\n";
   print "HOME DIR=$dir\n";
   print "Shell=$shell\n";
}

endpwent(); # Closes the database;
