This blog post has helped me clean up my postgres development environment on Mac. So making a copy!

If you used the EnterpriseDB installer , follow the following step.

docker build -t friendlyname .  # Create image using this directory's Dockerfile
docker run -p 4000:80 friendlyname  # Run "friendlyname" mapping port 4000 to 80
docker run -d -p 4000:80 friendlyname         # Same thing, but in detached mode
docker container ls                                # List all running containers
docker container ls -a             # List all containers, even those not running
docker container stop <hash>           # Gracefully stop the specified container
docker container kill <hash>         # Force shutdown of the specified container
docker container rm <hash>        # Remove specified container from this machine
docker container rm $(docker container ls -a -q)         # Remove all containers
docker image ls -a                             # List all images on this machine

Android Studio Shortcuts (Mac)

Notes:

• Two of the most useful shortcuts utilize the Fn (function) keys. It is therefore recommended that you enable the "Use all F1, F2, etc. keys as standard function keys" option [System Preferences > Keyboard].
• Be sure to enable the Mac OS X 10.5+ keymap in Android Studio [Preferences > Keymap].
• A fairly complete shortcut list can be found here.

Hit the Esc key; vim goes into command mode. Then you can type

:q to quit (short for :quit)
:q! to quit without saving (short for :quit!)
:wq to write and quit (think write and quit)
:wq! to write and quit even if file has only read permission (if file does not have write permission: force write)
:x to write and quit (similar to :wq, but won't write if there are no changes)
:qa to quit all (short for :quitall)
When you press :, a : will appear at the bottom of the screen.
