Git diff with line numbers (Git log with line numbers)

Question

When I do a git diff or a git log -p, how do I get line numbers of the source file(s) inlined with the output?

I tried to look it up

You can use git difftool to do the diff with an external editor that will display line numbers. Here's how to do it with vim / vimdiff:

1. Set vimdiff as git's difftool:

   git config --global diff.tool vimdiff
   

2. Configure ~/.vimrc to automatically show line numbers when using vimdiff:

   if &diff
       set number
   endif
   

3. Run git difftool, which will use vimdiff with line numbers:

   git difftool
