Novice question here...
How can I open a file, entirely remove all lines which start w/ 'Path: ' (without the quotes), and write the file to a new filename. I have tried several variations on this code:


open NEWSFILE, "<news_file.txt" or die "Can't open news_file.txt";

open TEMPFILE, ">temp_file.txt" or die "Can't open temp_file.txt";
while (<NEWSFILE>) {
      tr/Path: //;
      print TEMPFILE;


but no luck.

simply change these 2 lines:

  tr/Path: //;
  print TEMPFILE;


  print TEMPFILE if ! /Path:/;

That's all it takes.

The /Path:/ says print a line, unless 'Path:' is in the line.

If you want it to only check at the beginning of the line, change it to /^Path:/.

The 'tr' command you used says to translate the characters 'Path:' to nothing, which is exactly what happened, nothing. :)
