I wrote this script to keep a file or a folder in sync local or remotely. This worked out very well to sync changes in the code to a remote server in seconds without touching any button on my keyboard. The method to check if anything has changed is even simpler. It checks the file or folder last change date 'ls --full-time'.

Set the variable path to a directory or file. This could be a remote path aswell.

FP_rsync_from='/folder/from'
FP_rsync_to='/folder/to'

eval will set the variable to use Docker without the need to start "Docker Quickstart Terminal" eval takes a string as its argument, and evaluates it as if you'd typed that string on a command line. (If you pass several arguments, they are first joined with spaces between them.) eval $(docker-machine env)

Stop all docker container

docker stop $(docker ps -a -q)

Delete all docker container

docker rm $(docker ps -a -q)
