Subject: Re: [9front] sed bug?
Date: Tue, 13 Nov 2018 15:32:12 -0500	[thread overview]
Message-ID: <CAG2UyHrjv8cKgExs0THkiEfw-kQB2F35FrxP5fNX+-8Wq=6NdA@mail.gmail.com> (raw)
In-Reply-To: <20181113212806.523d19f7@gmx.de>

"1/test$/d" doesn't match the pattern "[address [, address] ] function
[argument ...]". There's a comma that separates the two addresses in
the documentation.
