Does anybody know why there are line breaks in the sed command?

It runs multiple expressions. That is

  sed '/pattern1/d
  pattern2/d'
is the same with

  sed '/pattern1/d; /pattern2/d'
and

  sed -e '/pattern1/d' -e '/pattern2/d'
I believe those are portable across all `sed` implementations, and they at least work with GNU `sed --posix` and plan9port's sed.

Thank you! This is exactly the kind of reply I was hoping for.
