Git Tips

git remote show origin
git config -l
git blame models/user.rb
git branch -a #List both remote-tracking branches and local branches.
git var -l
git diff --cached #git diff --cached to see what you’ve staged so far
git-clean - Remove untracked files from the working tree


This is particularly useful if you forgot to add something to your .gitignore file and accidentally added it, like a large log file or a bunch of .a compiled files. To do this, use the --cached option:
$ git rm --cached readme.tx

SSH is also the only network-based protocol that you can easily read from and write to. The other two network protocols (HTTP and Git) are generally read-only, so even if you have them available for the unwashed masses, you still need SSH for your own write commands.

In fact, it's pretty easy to see what the snapshot of your HEAD looks like. Here is an example of getting the actual directory listing and SHA checksums for each file in the HEAD snapshot:

$ cat .git/HEAD
ref: refs/heads/master

$ cat .git/refs/heads/master
e9a570524b63d2a2b3a7c3325acf5b89bbeb131e

$ git cat-file -p e9a570524b63d2a2b3a7c3325acf5b89bbeb131e
