in thread unwanted ARGV in subroutine

And if the file is huge, the OP shouldn't be loading it into memory, and should write to a temp file, and then rename it at the end.

    Hi rizzler

    Try this

    sub addheader{ my($infile,$header)=@_; open(FILE, "$infile"); my $text=do {local $/; <FILE>}; close FILE; open(FILE,">$infile"); print FILE $header; print FILE $text; close FILE; }
      Please don't try that :) it doesn't use error checking ... If you want to copy a file use File::Copy, for moving File::Move
