在Mac上使用open命令 打开程序 有大用 有大大用

在以前要打开文件都是先找到文件夹双击打开，打开某个文件夹也是的，今天突然发现在Mac上有个命令可以很轻送就打开文件或者文件夹，当然，前提是打开终端，哈哈，这个命令就是open命令。

示例:

open robots.txt

这样对文件进行编辑，很方便，保存一下就可以关闭文件了。

打开文件夹：

open css    

这样很简单就把文件夹打开了。

下面是open命令的一些参数，可以自己动手试一试。

macdeMacBook-Pro:public mac$ open --help

open: unrecognized option `--help'

Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-s ][-b ] [-a ] [filenames] [--args arguments]

Help: Open opens files from a shell.

      By default, opens each file using the default application for that file. 

      If the file is in the form of a URL, the file will be opened as a URL.

Options: 

      -a                Opens with the specified application.

      -b                Opens with the specified application bundle identifier.

      -e                Opens with TextEdit.

      -t                Opens with default text editor.

      -f                Reads input from standard input and opens with TextEdit.

      -F  --fresh      Launches the app fresh, that is, without restoring windows. Saved persistent state is lost, excluding Untitled documents.

      -R, --reveal      Selects in the Finder instead of opening.

      -W, --wait-apps  Blocks until the used applications are closed (even if they were already running).

          --args        All remaining arguments are passed in argv to the application's main() function instead of opened.

      -n, --new        Open a new instance of the application even if one is already running.

      -j, --hide        Launches the app hidden.

      -g, --background  Does not bring the application to the foreground.

      -h, --header      Searches header file locations for headers matching the given filenames, and opens them.

      -s                For -h, the SDK to use; if supplied, only SDKs whose names contain the argument value are searched.

                        Otherwise the highest versioned SDK in each platform is used.
