Open Current Folder in Finder from the Terminal
From the Terminal, you can immediately open whatever folder or directory you are working within into the Finder by simply typing the following command:
This will open the present working directory (PWD in the world of UNIX acronyms) in the Terminal / Command line into the Finder. So if you’re digging around in /Library/Preferences/Mozilla/ and type open . that folder will be opened in the Finder. The screenshot above shows this in action while the PWD within the Terminal is the /Applications directory, thus the Applications folder is opened in the Finder.
