Use git diff and git checkout to a file with a long path is sometimes time consuming. git-ck is created to simply this process.
OSX One-liner:
$ (cd /tmp && git clone https://github.com/iandai/git-ck.git && cd git-ck && sudo cp bin/git-ck /usr/bin/)
s Show result of git status -s.
diff [<number>] Show result of git diff of the files.
ck [<number>] Checkout the file.
exit Exit.
h Help.
