    Hi,

    How I can cat a file's contents through Perl-CGI. I want to write a Perl-CGI program which will accept file's name from a browser on Windows machine and then cat the contents of that file back to browser window. Any thoughts how to do this?

    Thanks in Advance,

    Here's the code

    Code:
    #!/usr/bin/perl
     
     use CGI;
     
     my $q = new CGI;
     
     $file = $q->param('file') || $ARGV[0];
     
     if(-f $file)
     {
         $txt = qx(cat $file);
     }
     else
     {
         $txt = "File doesn't not exist!";
     }
     
     print $q->header,$txt;

    Hey thanks Pradeep,

    But How I can take file name in IE on Windows? And Do I need to give this CGI script root access?

    Regards,

    Just like you do it in *nix, just that you need to have drive names in the beginning of the path/to/file.

    Well you needn't give the script root access, if you are running it from a Web Server apache needs to have read permissions to the file.
