• open 打开

  Usage: open [-e] [-t] [-f] [-W] [-R] [-n] [-g] [-h] [-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.

• alias “同名”

  可以用在bash、zsh配置文件中，使前者与后者等价
  
  ```bash
      alias typora="open -a typora"
  ```
