How to open a file via Mac Terminal

If you are working on the Mac Terminal and want to see the contents of a file on an external app like TextEdit (default text editor for macOS) then you can make use of the open command.

Open File in TextEdit

% open -a TextEdit ~/Desktop/sample.txt

In a similar way if you have other Text Editors installed on your Mac you can open files with them as well,

Open File in Sublime Text

% open -a TextEdit ~/Desktop/sample.txt

Open File in Default Text Editor

% open  ~/Desktop/sample.txt

You do not need to pass in any options with open command to open the file in the default text editor.

Note: You can open any type of file using the open command, let's try to open an mp4 video file.

% open  ~/Documents/holiday.mp4
