Hi
I saw now days this command no longer is working. giving exception with command argument.

git ls-remote https://github.com/docker/compose | grep "refs/tag" | grep -oP "[0-9]+.[0-9]+.[0-9]+"
usage: grep [-abcDEFGHhIiJLlmnOoqRSsUVvwxZ] [-A num] [-B num] [-C[num]]
[-e pattern] [-f file] [--binary-files=value] [--color=when]
[--context[=num]] [--directories=action] [--label] [--line-buffered]
[--null] [pattern] [file ...]

Thanks !
