Maybe someone has also installed Haskell with ghcup... which makes rm -rf ~/.ghcup useful.

Thanks for this! One small modification:

rm -rf ~/.cabal
rm -rf ~/.ghc

Right?

Good call!

I haven't used a Mac for 6 years so my apologies to everyone if this isn't perfect!

Or run:
$ uninstall-hs

Some files/folders require sudo but in sudo there is no uninstall-hs of course. Just use the full script by @gatlin to avoid even more complications.

When I run the last command sudo rm 'cat /tmp/hs-bin-links' I have the following warning:

usage: rm [-f | -i] [-dPRrvW] file ...
       unlink file

What does it mean?

When I run the last command sudo rm 'cat /tmp/hs-bin-links' I have the following warning:

I guess you are using the single quote instead of the grave accent.

I used a single quote for properly displaying the statement. Even if I use the grave accent, still I have the same warning. I'm not familiar with the bash terms. I guess the warning means "No folder named hs-bin-links"?

sudo rm -rf /usr/local/lib/HaskellCLI-8.6.4-13.14-2

Hi @olivier-text100

Or run:
$ uninstall-hs

Where should I expect uninstall-hs to be found?

It is not in my path and looking for up I turn up nothing.

What about .ghcup?
