Backticks are for when you want to capture the output of some shell command. In this case, you're redirecting output to a file, so backticks won't do that. Your backticks also don't give you anything in a void context.

That said, putting the same thing in system won't help either. It's the underlying grep that's hanging.

I think that grep needs to get some arguments. You could do this, minimally: 

`grep -v $removeq $sourcefile /dev/null /dev/null > $tempfile`;

That won't hang, but it also won't work until $removeq and $sourcefile are right. You probably ought to be passing them in initially: 

&clean_the_file( $sourcefile, $removeq );

[download]

I can't tell what $sourcefile should be, though.

Hope this helps.
