Thank you very much for you answer. It works but there is a problem: I would to successfully match the string if '#foo' is not there (0 or 1 occurences)

It already does do that. Specifically, it always matches, setting `$1` to `foo` if `#\w+` is found at the start of the string, and setting `$1` to undef otherwise.	[reply] [d/l] [select]

That said, I believe it has other problems. It doesn't set `$1` to `foo` when matching against `bli #foo bla`. It doesn't set `$1` to the empty string when matching against `bli bla`. However, it does set it to undef, which might be close enough.	[reply] [d/l] [select]
