Let’s say we just executed the following command:
grep 'foo' foo.md
It gave us the information we were looking for and now we want to execute
a similar command to find the occurrences of
trick won’t quite work here.
$ ^foo^bar<tab> grep 'bar' foo.md
What we need is a global replace of
foo in our previous command. The
command can help when we sprinkle in some
$ !!gs/foo/bar<tab> grep 'bar' bar.md
For a short command like this, we haven’t gained much. However, for large commands that span the length of the terminal, this can definitely save us a little trouble.
