M-x grep gets /dev/null automatically appended to the command

M-x grep gets /dev/null automatically appended to the command

[Francis Moreau]

Hello,

I have customized my grep-command variable this way:

(setq grep-command "git --no-pager grep -n -e ")

because I'm working in a git repo.

But when I start the grep command (M-x grep), emacs appends
'/dev/null' to the git command:

git --no-pager grep -n -e seq /dev/null

Can anybody tell my what I'm doing wrong ?

thanks

Indeed I force it to nil and it magically works. Thanks !

Other topic: it looks like you're using gnus and newsgroup to post/reply on this
list. Is it possible to CC me when you're replying ?

I normally do that with mailing lists and not with newsgroups.  It's
possible either way, of course, but with newsgroups I do it rarely
enough that I just write the recipient in by hand.

Just of curiosity, how do you do that with newsgroups ? any special key bindings
or do you just add Cc field ?

No.

Just try what you suggested and you will see there's no Cc field
in your follow up.

I do it by hand.  You could automate it, but the trick would be
extracting the e-mail address to use.  Maybe the attribution line
would be the easy way to do it.  Maybe putting it in the followup
command would be better than doing it afterwards -- I don't see any
existing commands to do that, but a wrapper around the followup
command should do it.

We can answer to all recipients with Gnus' "Wide reply and yank" (S W)
feature. It will put the person you are replying to to the "To" field
and other people (as well as the mailing list address) to the "Cc"
field.

OK, at least I haven't missed that part.

It's a bit strange there's not already such command specially since
a lot of people out there do not use news readers. And in that case the
thread is simply broken and in that case it's hard to see that someone
reply.

BTW, it seems that you haven't used news group this time, have you ?

If so, it explains why this time you reply to _me_ and Cc the mailing
list...
