[Solved] Is there a typo in the last news? Answer:No.

The procedure to correctly update the filesystem package, propose this command to verify the presence of external packages which install inside the old binaries directories

$ pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm -

but I think that the last dash make that pipe useless. Am I wrong?

Piping to 'pacman -Qm' means only foreign packages (ones that are not in the official repos) will be printed.

Yes I know, in fact I'm talking about the last dash ( - )
I think this is wrong

$ pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm -

and this should be right

$ pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm

Sorry, pressed 'submit' instead of 'preview' ...

The dash is not useless - try without it - it will give you different (wrong) output. Why is it wrong is left as an exercise to the reader ;P

man pacman wrote:

if stdin is not from a terminal and a single dash (-) is passed as an argument, targets will be read from stdin.

I don't want seems presumptious, but this what I obtain with your command

javier@Archbox ~ $ pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm -
javier@Archbox ~ $

and this is what dash-less version return to me

those are all packages installed from AUR. I think this last one is the expected behaviour.

alphaniner · 2013-06-07 13:25:02

No, the dash is what makes it worthwhile. Without it, you'd just get the same output you get if you ran 'pacman -Qm' by itself.

For example, pretend the foreign package foo contained files in /bin.

$ pacman -Qqo /bin /sbin /usr/sbin
foo
filesystem
filesystem
filesystem
$ pacman -Qqo /bin /sbin /usr/sbin |pacman -Qm -
foo
$ pacman -Qm foo filesystem filesystem filesystem      #this is what the above command 'resolves to' (I think)
foo
$ pacman -Qqo /bin /sbin /usr/sbin |pacman -Qm
<all my foreign packages>
$ pacman -Qm
<all my foreign packages>

That's the expected behaviour of pacman -Qm by itself: listing all foreign packages. The point of the compound command in the news is to list the foreign packages which contain files in /bin /sbin and /usr/sbin.

Yes you're right, effectively these are all the packages from AUR, not just the ones which install into the old directories. Sorry for my error.
I think this thread can be safely deleted if you think so.
Thanks to everybody.

alphaniner · 2013-06-07 13:36:49

It's unlikely to be deleted. Just mark it [Solved]. Should probably also mention in OP that you were mistaken, so as not to mislead anyone. Or maybe you could mark the thread [Solved: No there isn't].

karol · 2013-06-07 13:37:46

Just mark it solved.
You're not the first one to wonder about the dash: https://bbs.archlinux.org/viewtopic.php … 3#p1282803

Done. Next time I'll search better inside the forum.

Mr.Elendig · 2013-06-14 10:24:20

You might want to look at this video http://www.youtube.com/watch?v=pXhcPJK5cMc, posix http://www.unix.org/version3/pr.html and the pacman manual.

Firstly, I also thought there was a typo at the "paclist" step, but then I saw I had to manually replace <repo> with the configured repos on my system (I blame my low intelligence).
And I would like to also add that there should be a step 4 after the final updating the system: mkinitcpio -p linux (or linux-lits or linux-ck). I didn't do that and was stuck a little longer than I should have been.

Not relevant to the news item. You don't have to rebuild the initcpio due to this change.
