搞定直接在终端中 cd 到 Finder 目录，兼容（iTerm2/TotalFinder）

完整代码：

```
# cd Finder path
# 兼容 Finder/TotalFinder、Terminal/iTerm2，兼容 Finder 处于隐藏或最小化状态
# TODO：在处理隐藏或最小化状态时没有找到合适API，实现太绕
function cd.() {

# 检查 Finder 是否执行
if [ "`osascript -e 'tell applicaton "System Events" to "Finder" is in (get name of processes)'`" = "true" ]; then

# 检查当前状态是否可以获取路径
if [ "`osascript -e 'tell application "Finder" to get collapsed of front window' 2>/dev/null`" != "false" ]; then

if [ "`osascript -e 'tell application "System Events" to "TotalFinderCrashWatcher" is in (get name of processes)'`" = "true" ];then

# 隐藏TotalFinder(最小化（commond+m）报错)
open .
osascript -e 'tell application "System Events" to tell process "Finder" to keystroke "w" using {command down}' -e 'tell application "System Events" to tell process "Finder" to keystroke "h" using {command down}'
else

# 最小化Finder(隐藏状态(commond+h) 报错)
finderState=`osascript -e 'tell application "System Events" to set visible of application process "Finder" to true' -e 'tell application "Finder" to set collapsed of front window to true' 2>/dev/null`
fi
fi

finder=`osascript -e 'tell application "Finder" to set curName to (POSIX path of (target of front window as alias))' 2>/dev/null`

# 检查返回值是否为空字符串
if [ -z "$finder" ]; then
echo "Failed to find \"Finder\""
else
echo "$finder"
cd "$finder"
fi

else
echo "\"Finder\" is not running"
fi
}
```

将上面代码添加至 ~/.bashrc 后，即可享用cd.（结合open .来去自如了）
