Open is a fairly advanced command, as a friend of mine put it, it is heavily modded.

It can amongst other things take a stream and open it in TextEdit, it can make the foreground window of an app come to front. It can open an app in the background, it can also open specific apps..

A read of its man page is recommended: "man open" in a Terminal window.

This brings the Finder window for CWD (current working directory) to front from the Terminal window:

open -b "com.apple.finder" .

Observe the dot at the end of the command!

A very cool use ofopen is when you use the -n option to open an application. It opens a new instance of an application whether or not another one is already running. BTW don't follow the installation instructions on the github page if you have customised your ~/.bash_profile file, as it completely overwrites it, and none of the stuff in it is actually relevant.
