Automatically link a dir and contents with a Github repo of the same name

snippet.sh

#!/bin/bash
#######################################################################################
## save as "github" in your path, and chmod+x
## Takes one optional argument: a directory name (new or existing)
## in which to create the repo (script assumes it's the same name as the Github repo)
## if called without an argument, assumes you wish to use the current working directory
## example: "github foo" creates (if it doesn't exist) dir foo in current working dir
## switches to foo initialises git repo, adds files, performs initial commit, 
## sets remote master to [email protected]:github_user/foo.git and
## attempts to push to it. If the push fails, .git dir is removed and the script exits
## with code 1
## substitute your github username for git_user, on line 14
