檔案在 git pull 後被刪除、可以用 git fsck 救回來

fsck-git-log.sh

# 這個時候檔案都已經做完，想要放到 Github 上
josephj@cockatoo /var/www/josephj/frontend/lab/2012/qt-webkit $ % git init .

josephj@cockatoo /var/www/josephj/frontend/lab/2012/qt-webkit $ % git remote add origin git@github.com:miiicasa/tv-apps-html.git

# 先試著從 Github 上抓東西下來

 * [new branch]      master     -> origin/master
You asked me to pull without telling me which branch you
want to merge with, and 'branch.master.merge' in
your configuration file does not tell me either.        Please
specify which branch you want to merge on the command line and
try again (e.g. 'git pull <repository> <refspec>').
See git-pull(1) for details.

If you often merge with the same branch, you may want to
configure the following variables in your configuration
file:

    branch.master.remote = <nickname>
    branch.master.merge = <remote-ref>
    remote.<nickname>.url = <url>
    remote.<nickname>.fetch = <refspec>

See git-config(1) for details.
