*README.md

Create Custom git.io Short Links

Add this helper function to your ~/.bash_profile (or ~/.bashrc, or whatever you use) to create custom short links for your GitHub projects without having to remember the whole cURL command!

Installation

If you use a file other than ~/.bash_profile to configure your terminal, substitute that value in the installation instructions below.

1. Open your ~/.bash_profile
2. Copy-paste the gitlink function into it
3. Save the file
4. Run source ~/.bash_profile

Usage

To create a git.io short link:

gitlink $url_to_shorten [$custom_short_code]

$ gitlink https://github.com/gramps-graphql
# => https://git.io/vxnTa

To specify a custom short link:

$ gitlink https://github.com/jlengstorf/bemmit bemmit
# => https://git.io/bemmit

NOTE: Custom short links can only be assigned if A) no short link has already been created for the long URL and B) the custom short link is not already in use.

gitlink.sh

# Shortcut function for creating custom git.io links.
# See https://blog.github.com/2011-11-10-git-io-github-url-shortener/
gitlink() {
  # The first argument is the URL to shorten
  VALUES="-F \"url=$1\""

  # If a custom short code was requested, set the form value.
  if [ -n "$2" ]; then VALUES="$VALUES -F \"code=$2\""; fi

  # Send the request to GitHub and grab the Location header.
  RESPONSE=$(eval "curl -i https://git.io $VALUES 2>&1" | grep Location)

  # Remove the header name and echo only the generated short link.
  echo "${RESPONSE//Location: /}"
}
