How does pacman -R work to remove an application?

Hi All, I want to know how pacman -R work to remove an application.

Does it use the 'rm' utillity to remove the application's files? If so, can I let pacman to use 'srm' instead of 'rm'? If it is possible, how?

It uses unlink(2), which is the same system call rm uses, and you can't make it use something else without modifying the code.

Relevant code is in lib/libalpm/remove.c.

How 'bout, how do I see where a package that I've installed is installed to?
So, I can remove normally with pacman and remove the left overs by my self later.

You can see all the files installed by a package like this:

pacman -Ql package

However any files that are created by the program post-installation (maybe config files or something) will not be in the list.

Thanks, that was helpful.

Btw, the "any files that are created by the program post-installation (maybe config files or something)", are those files the so-called 'dot files' in the user's home directory?

Yes it's about the dotfiles, files in ~/.config etc.

That would include /etc too.

Only if the app is run using root.
