Easily create branch names from pasted story titles.

.gitconfig

[alias]
	br- = "!f() { git branch $(dasherize \"$@\"); }; f"
	cob- = "!f() { git checkout -b $(dasherize \"$@\"); }; f"

dasherize

#!/bin/bash

echo -n "$@"                   \
  | tr '[:upper:]' '[:lower:]' \
  | tr '_' ' '                 \
  | tr -d '[:punct:]'          \
  | tr -s '[:space:]' '-'

You'll probably want to rename the git aliases to something that makes more sense to you. Or you could ignore the aliases and change the dasherize script to create the branch.

The aliases aren't smart enough to allow for additional option flags to be passed in so watch out for that.
