I assume Over here, $var doesnt work means $var has nothing in it. Did you tried printing the $var to a file? When you said print $var, it prints the contents to the STDOUT, which is captured by the system function in PHP. So print $var seems not printing anything, but actually it has the output. `$bar=$ARGV[0]; $lak=system($bar); print $lak; #This will be captured by the system function in the PHP f +ile. open FH,">> llll"; print FH $lak;` [download] Now the file will also have the output	[reply] [d/l]

$bar=$ARGV[0];

open FH,">> llll";
