Pacman -Scc --noconfirm doesn't clean the cache because the first question default answer is N. Is this in purpose, or is it a bug?

My workaround is to do:
echo -e 'y\ny' | /usr/bin/pacman -Scc
This task depends upon

--noconfirm do not ask for any confirmation

In other words, put a default in all questions.

you can use "yes" command for that purpose (instead of echo...)

So it is normal for this command not to actually perform anything? It's just a dead combination of options...

In general, pacman defaults to the safest answer. But I am with jimis here: User (script) should know what -Scc and means (moreover, he is asked), and I don't think that it is a more dangerous operation than -Rc (where the default is Y).

Btw, there is a hidden and undocumented --ask switch to answer these questions, but it is for internal usage only (the syntax is complicated, it requires a bitvector etc.)

I am not sure what we could do differently.
But people should not use pacman -Scc anyway...
And there is already plenty of options :
1) use echo y or yes
2) rm /var/cache/pacman/pkg/*
...

Well, I wanted to say that in my opinion the Y default answer would be more coherent here (see also -Sc). But changing the default answer is maybe worse than changing nothing.

The idea is that -Scc is more destructive than -Sc , and is not advised.
It's recommended to keep installed packages for two main reasons :
1) reinstall (because its broken, or files were lost, or need to change install reason)
2) downgrade after an upgrade

Well, I use -Scc when I need more free disk space. ;-)

I don't think that someone uses -Scc "accidentally". If someone does, we ask a "Do you want to ... ALL ...?" question.

But OK, this is a minor issue(?), I am fine with "won't implement", too.

Now I understand why most programs prefer having a --yes flag rather than a --no-confirm. It's clear to the user that the outcome won't depend on the default answer.

yes | pacman -Scc works as well as any of the other previously mentioned methods
