Rather than having the output write the line unless it equals
search_text, I need it to write when it equals search_text. I know that
should be easy, but I can’t find the syntax.
outfile.write(line) unless line =~ search_text

try if instead of unless

Using if instead of unless is definitely clearer here, but you can also
negate the match operator by replacing =~ with !~ as follows:
outfile.write(line) unless line !~ search_text
Double negatives are usually unnecessarily hard to understand at a
glance though, so use the if statement instead of unless here.
