Linux commands: open

A quick guide to the `open` command, used to open files, directories and applications

The open command lets you open a file using this syntax:

open <filename>

You can also open a directory, which on macOS opens the Finder app with the current directory open:

open <directory name>

I use it all the time to open the current directory:

open .

The special . symbol points to the current directory, as .. points to the parent directory

The same command can also be be used to run an application:

open <application name>

The open command works on Linux, macOS, WSL, and anywhere you have a UNIX environment
