Instead of stringing together sed multiple times in a pipeline, it is also possible to make multiple substitutions with a single invocation of sed.
Consider the following example which replaces the word ‘hello’ as well as ‘quick’ in the paragraph:
$ sed "s/hello/goodbye/g; s/quick/slow/g" <<EOF hello, world! hello, universe! the quick brown fox EOF goodbye, world! goodbye, universe! the slow brown fox
The semicolon is the separator of the sed commands.
