Converts UNIX file permissions to absolute mode. ( ie. rwsrwxrwx -> 4777 ). This is useful when you don't have the file locally .. just the output of the listing of the file. (Ex: Using Expect to access a remote system and obtaining data via shell commands )
#!/usr/local/bin/perl

$a = <>;
chomp( $a );
@p0{"-","r"} = ( 0, 400 );
@p1{"-","w"} = ( 0, 200 );
@p2{"-","x","s","S"} = ( 0, 100, 4100, 4000 );
@p3{"-","r"} = ( 0, 40 );
@p4{"-","w"} = ( 0, 20 );
@p5{"-","x","s","l"} = ( 0, 10, 2010, 2000 );
@p6{"-","r"} = ( 0, 4 );
@p7{"-","w"} = ( 0, 2 );
@p8{"-","x","t","T"} = ( 0, 1, 1001, 1000 );
@a = (\%p0,\%p1,\%p2,\%p3,\%p4,\%p5,\%p6,\%p7,\%p8);
$perms = 0;
$result = `ls -lLd $a | awk '{print \$1}' | cut -b2-10`;
chomp( $result );
print "$result\n";
for ( $x = 0; $x <= 8; $x++ ) {
        $b = substr( $result, $x, 1 );
        print "char -> $b position -> $x ";
        print "value -> $a[$x]{substr( $result, $x, 1 )}\n";
        $perms = $perms + $a[$x]{substr( $result, $x, 1 )};
}

print "perms -> $perms\n";
