Hi,

I just can't get my head around this and I'm sure its so simple I'm going to feel stupid having asked the question but here goes.

What I'm trying to do is use $ENV{'SCRIPT_FILENAME'} as the path to the script and then as I know the name of the script substitute that name for the names of other files in the same directory the permissions of which I will than go on and change.

Here's a small debugging script I'm playing with to try and get this to work. 

#!/usr/bin/perl

@filelist =("includes.cgi","connect.cgi","commit.cgi");

print "Content-type:text/html\n\n";

$path = $ENV{'SCRIPT_FILENAME'});


foreach $filelist (@filelist){
        $path =~ s/permissions.cgi/$filename/gi;
            print "$filelist -- $path<br />";
}

I'd be very grateful if some kind Monk could show me where I'm going wrong, or suggest an alternative way of "sensing" the path to files.

Many thanks

Sid
