Pacman and uninstalling multiple packages

I'm having trouble with haskell-pandoc install as described here [1]. After using `#pacman -R` on a few of these packages, I was able to complete my pacman update. The trouble is, I had to uninstall on one package at a time, and there's a bunch in the haskell group.

I tried several suggestions here in forums to remove these packages, but I'm not getting anywhere:

$ sudo pacman -R $(pacman -Qq | grep haskell)
error: only one operation may be used at a time

$ sudo pacman -R $(pacman -Ssq haskell)
[...]
warning: skipping target: haskell-sha
warning: skipping target: haskell-stm
[...]
error: target not found: haskell-x11
warning: skipping target: haskell-zlib
error: target not found: xmonad

Any suggestions?

Re: Pacman and uninstalling multiple packages

You might want to take a closer look at what options do, since pacman -Ssq haskell won't do what you want, suggesting you were typing in commands without knowing what they do. And if haskell is actually a group pacman -Qqg will be closer to what you want, plus you probably want to look for dependencies that should be removed as well.

But if you need to remove any packages containing the word haskell

 sudo pacman -R $(pacman -Qq | grep haskell)

should have worked so it might also help to look at/post the output of just

pacman -Qq | grep haskell

Re: Pacman and uninstalling multiple packages

Usually 'pacman -R foo' is a bad idea, since it may leave orphans behind.

Yes and no. The output from the inner `pacman` call in each example above does, in fact, produce a list of packages with `haskell`.  The outer call to pacman does not work as the posted examples suggest. The only clear difference is the examples were for installing and I'm trying to remove packages.

pacman -Qqs

I really strongly suggest you look at pacman's manual. You have been warned about help vampirism before.
