| Purpose | Command | Description | Example |
|---|
| List courses | ./gte | List all available courses to run. For most courses, 2 docker images exist-- A starting image named COURSE.1, and an image that is in the expected end state called COURSE.end. E.g. "201.1.1" and "201.1.end". Normally, you are not expected to start and stop containers between exercises. |

| Run a course | ./gte <course> | This will stop all GTE docker containers running, and will start the one specified. It will also stop/start the rabbitmq messaging container. Only one course can run at a time due to network port requirements. |

| Shell into running container | ./gte-shell
exit | A container is a virtual operating system that you can go into and investigate, look around, troubleshoot. Note, this will not work if you are not running a container. Start a container before shelling in. Note, containers are ephemeral, if you change the contents in a container they will be lost when the container stops. Note, when done with the shell, type exit to return to the host (outside container). |

|
| GSH into a container | ./gte-gsh
:q | GSH or Grouper Shell is a command line Java interface into Grouper. It is useful to run commands or to script multiple commands. It is only available for Grouper admins. Note, this will not work if you are not running a container. Start a container before GSH'ing in. Note, when done type :q to quit and return to the host. |

| View logs of a running container | ./gte-logs
CTRL-c | Note, this will not work if you are not running a container. Start a container before viewing logs. Once a container is stopped in the GTE the logs are gone. Type CTRL and c to return to the host. |
