in reply to Append to beginning of line (multi line file)

You could just open and write the last one at the end. This should also fix your numbering problem.
open(INPUTFILE, "$file"); open(OUTPUTFILE, ">$outputfile"); my $counter = 1; while (<INPUTFILE>) { print OUTPUTFILE "$counter. $_"; $counter++; } close(INPUTFILE); close(OUTPUTFILE);
If you want to copy over the old file, just do it at the end.

UPDATE: You should probably check to make sure the files actually open (using die) like you did in your original code.

UPDATE2: Only now does command line register in krujos' head. Doh!
