Works for me: $ echo "a cat or a dog" | sed 's/\(cat\)\|\(dog\)/PET/g' a PET or a PET The \(...\) aren't necessary, since the \| has low precedence. $ echo "a cat or a dog" | sed 's/cat\|dog/PET/g' a PET or a PET $ sed --version GNU sed version 4.1.5 Copyright (C) 2003 Free Software Foundation, Inc.
