How to uninstall/delete software not installed through Pacman.

Question

I tried to search for an answer, with limited success. I have installed some stuff from external sources using various installers. In particular, I installed some stuff from Humble Bundle which, if I recall correctly, used this automated installer called Nixstaller, which I thought would register the packages in Pacman. And when I look at the website, it says that if it fails to register the software in the package manager, it will generate an uninstall script. I installed e.g. Torchlight in /usr/local/games, but there is no uninstall script to be found there, or in the generated folder in /home. Neither does it seem to be registered in Pacman. So how do I get rid of it? Is there a way to uninstall it, or would I have to remove everything manually? If I have to remove it manually, how do I know where everything is located? I assume the installation isn't necessarily limited to the /usr/local/games folder I picked and /home, so how would I go about getting rid of it all?

Answer 1

Not to my knowledge.  You can ask pacman to show you ALL files not owned by a package and then begin to manually delete ones you feel do not belong.  Note that you should NOT just blindly start removing these!
Here is ~/bin/pacman-disowned that I got from here; can't remember who authored it.
#!/bin/sh
tmp=${TMPDIR-/tmp}/pacman-disowned-$UID-$$
db=$tmp/db
fs=$tmp/fs
mkdir "$tmp"
trap 'rm -rf "$tmp"' EXIT
pacman -Qlq | sort -u > "$db"
find /bin /etc /lib /sbin /usr \
! -name lost+found \
\( -type d -printf '%p/\n' -o -print \) | sort > "$fs"
comm -23 "$fs" "$db"|less
