The portable way is to use multiple "-e" parameters:

  $ echo abcde​ | sed -e 's/cd/XX/' -e 's/[^x]/z/ig'
  zzXXzz

That should work on all sed, not just gnu sed.

When using GNU sed, you can specify multiple commands
separated by semicolons:

  $ echo abcde​ | sed 's/cd/XX/ ;  s/[^x]/z/ig'
  zzXXzz


I'm closing this item but discussion can continue by replying
to this thread.
