Git Demote
I'm a big fan of Trevor Squires' Git Promote script, but one thing that's bothered me about it since I started using it is that it tends to clutter up my .git/config file. So, I made a counter-script for it that I'm calling, appropriately, "git demote"
#!/bin/sh
#
# Counter-script to Travis Squires' git-promote script
# (http://hoth.entp.com/2008/11/10/improving-my-git-workflow)
# Removes a 'promoted' branch from the git config file.
curr_branch=$(git symbolic-ref -q HEAD | sed -e 's|^refs/heads/||')
git config --remove-section "branch.${curr_branch}"
To install it, simply create a file called $HOME/bin/git-demote (assuming you have $HOME/bin in your PATH, otherwise place it somehwere that does exist in your PATH), then run the following from the terminal:
$ chmod 755 $HOME/bin/git-demote
Now, when you're done with a branch, you can clean up your .git/config file by running:
$ git checkout topic-branch
$ git demote
And you're good to go.
You can fork the Gist, if you don't want to type all that.
