Disable auto-completion of remote branches in Git Bash?

Question

I\'m working on a fairly large git repo with a couple of thousand (remote) branches. I am used to using auto-completion (using [TAB]) in the console (Git Bash in that case),

Answer 1

Carey Metcalfe wrote a blog post containing a solution that also edits the auto-completion function, but with slightly newer code than other answers. He also defines an alias checkoutr that keeps the old auto-complete behavior in case it’s ever needed.

In short, first create the checkoutr alias with this command:

git config --global alias.checkoutr checkout

Then find git-completion.bash, copy the _git_checkout function into your shell’s RC file so that it gets redefined, and inside that function, replace this line:

__git_complete_refs $track_opt

with the following lines:

if [ "$command" = "checkoutr" ]; then
    __git_complete_refs $track_opt
else
    __gitcomp_direct "$(__git_heads "" "$cur" " ")"
fi

See the blog post for more details and potential updates to the code.
