repo diff 导出

REPO 是Android Source 的同步工具，使用repo diff可以查看修改过的文件，那么使用repo diff > xxx.diff就可以将内容导出成为文件

像普通的diff文件一样patch

使用google group一个人的代码：https://groups.google.com/forum/#!topic/repo-discuss/43juvD1qGIQ

## Script to patch up diff reated by `repo diff`

if [ -z "$1" ] || [ ! -e "$1" ]; then
    echo "Usages: $0 &lt;repo_diff_file&gt;";
    exit 0;
fi

rm -fr _tmp_splits*
cat $1 | csplit -qf '' -b "_tmp_splits.%d.diff" - '/^project.*\/$/' '{*}'

working_dir=`pwd`

for proj_diff in `ls _tmp_splits.*.diff`
do 
    chg_dir=`cat $proj_diff | grep '^project.*\/$' | cut -d " " -f 2`
    echo "FILE: $proj_diff $chg_dir"
    if [ -e $chg_dir ]; then
        ( cd $chg_dir; \
            cat $working_dir/$proj_diff | grep -v '^project.*\/$' | patch -Np1;);
    else
        echo "$0: Project directory $chg_dir don't exists.";
    fi
done

将该文件保存为sh并且加上执行权限，就可以使用./xxx.sh xxx.diff打补丁了。。注意文件位置
