Archives

I frequently find that I have old projects that I don't necessarily want ot delete, but I want to get out of the way. This is my setup to make that easy.

My setup has two parts: A repo (ex. ariporad/archive), and a script (this one):

• The repo This repo is a collection of orphan branches, one per project. Since some of these projects are private (and I'm lazy), the entire repo is private.
• The script This script takes the name of a file/folder ($folder) as an argument. It then:
  1. Zipps it into a temporary directory ($tmpdir), and appends the datetime to the folder name.
  2. Creates a new git repo in $tmpdir, and commits everything.
  3. Adds the archive repo as a remote
  4. Tries to push to $branch ($branch = $folder, all lowercase).
  5. If that fails, it: 1. Fetches origin 2. Rebases onto origin/$branch 3. Pushes again (if that fails, display an error and exit).
  6. Deletes $tmpdir

This was really useful for me, and it also cleaned up some hard drive space, which I was lacking. I hope you like it.

Welcome to the Archiver!
This utility makes it easy to archive a project you no longer need!

It works if it ends with 'OK'.

Here's what's about to happen:
    1. The project (a.k.a the folder \`$1\`) will get zipped in to a
       temporary directory (./$OUTPUT_ZIP).
    2. That dir will then be pushed to an orphan branch called \`$GIT_BRANCH\`
       in \`$GITHUB_REPO\` on GitHub. (\`$GITHUB_REPO#$GIT_BRANCH\`).
    3. \`./$1\` will be moved to trash.
