You can also edit "in place" so that it actually looks as deleting the lines you don't want from the original file. Modifying HBM's example, this could look like this:

perl -i.bak -ne 'print unless /dontwant/' my_file.txt

There, unwanted lines will be removed from my_file.txt and the original version of the file will be saved with the .bak extension added.
