给你一个git自动操作脚本（切换分支，更新，是否有新文件）

把以下代码保存为update.sh，然后要改些东西我简单标注下，不懂也没关系，反正你也不会问的，问我就告诉你，用法是这样的

sh update.sh -c -p -g master

作用是将指定的库切换（-c）到指定分支（master），并更新（-p），检查是否有新内容（-g）

#/bin/bash

work_path="/Users/local/Broken";    ：修改标红为本地工程绝对路径'


git_checkout()
{
if [ $2x = x ]; then
echo "Switch to Witch Brnach?";
exit 1;
fi
cd $work_path/$1;
git checkout $2
if [ "$?" = "0" ]; then
echo -e "Git Checkout $2 \033[32m SUCCESS \033[0m";
else
echo -e "Git Checkout $2 \033[31m Failed \033[0m";
fi
}


git_pull()
{
if [ $2x = x ]; then
echo "Pull Witch Brnach?";
exit 1;
fi


cd $work_path/$1;
cur_branch=`git branch | grep "*" | awk {'print $2'}`;
if [ "$cur_branch" = "$2" ]; then
git pull origin $2:$2 -q
if [ "$?" = "0" ]; then
echo -e  "Git Pull $1 on $2: \033[32m SUCCESS \033[0m";
else
echo -e "Git Pull $1 on $2: \033[31m FAILED \033[0m";
fi
git log -n 1
else
echo "Check To Branch $2 first, Current is $cur_branch";
exit 1;
fi


}


usage()
{
echo "Usage ./update_service.sh [-cpg] [branch name]";
}


echo "Current Work Path:$work_path"


if [ $# -lt 1 ]; then
usage;
exit -1;
fi
