git cheat-sheet

The git command-line utility has plenty of inconsistencies http://steveko.wordpress.com/2012/02/24/10-things-i-hate-about-git/

A GUI like http://sourcetreeapp.com is often helpful, but staying on the command line usually quicker. This is a list of the commands I use most frequently, listed by funcional category:

current state

git status list which (unstaged) files have changed

Docker

docker build . will run the Dockerfile to create an image
docker build . -t [Dockerhub-username]/[image-name]:[v1] build an image with a specific version
docker push [Dockerhub-username]/[image-name][v1] push to dockerhub
docker images will print all the available images
docker run {IMAGE_ID} will run a container with the image
docker run -d {IMAGE_ID} will run a container with the image in the background
docker ps will print all the running containers
docker kill {CONTAINER_ID} will terminate the container

	// Just in case, make sure the textfield isn't editable by the user
	$( '#resetpassform input[id=\'user_login\']' ).attr( 'readonly', true )
