This is a line tool to open anything you like with chrome.

• If you want to open localhost:8001, then you can use command o --p 8001
• As I'm a Mac user, so I set apache always start. The root directory is /Users/username, and port is 8080.
  • So if I want to open a file, and the file's directory is /Users/username/demo/css/index.js. You can use command like this.

    cd
    o /demo/css/index.js
    
    or
    
    cd /demo/css
    o index.js
    

  • It can also open a directory, not only file. Use command o /demo
