    How to open Visual Studio Code via command line

In order to open a Visual Studio Code sometimes we want to do it from the command line.
Either because that allows us to just open the current file or folder, or because we would like to script opening
some specific resource. This resource may be placed in another machine (e.g. via ssh), or in a docker container (running in
the same machine or in another machine).
Local file or folder

code <file or folder>
# e.g. code .
Remote-ssh

Thanks to this thread.
Note that you need the Remote - SSH extension installed.
# With 192.168.1.100 being the IP of the machine with the folder to open
code --folder-uri "vscode-remote://ssh-remote+192.168.1.100/home/myuser/myfolder/"
Docker container

Note that you need the Remote - Containers extension installed. Note that I found the attached-container+ code
by starting Visual Studio Code with --verbose and looking at the output when I connected manually.
# Encode the following config in HEX with your container name (test here):
# {"containerName":"/$CONTAINER_NAME"}
printf {\"containerName\":\"/test\"} | od -A n -t x1 | tr -d '[\n\t ]'
# Outputs for me 7b22636f6e7461696e65724e616d65223a222f74657374227d
code --folder-uri "vscode-remote://attached-container+7b22636f6e7461696e65724e616d65223a222f74657374227d/home/user/myproject"

# In a scriptable manner
CONTAINER_NAME=vigorous_mestorf
FOLDER=/home/dockeruser/myfolder
HEX_CONFIG=$(printf {\"containerName\":\"/$CONTAINER_NAME\"} | od -A n -t x1 | tr -d '[\n\t ]')
code --folder-uri "vscode-remote://attached-container+$HEX_CONFIG$FOLDER"
Remote docker container

Note that you need the Remote - Containers extension installed. You may also need your SSH key to be installed (ssh-add-key -i ~/.ssh/id_rsa user@192.168.1.100) in the target machine.
# With 192.168.1.100 being the IP of the machine with the docker container running
export DOCKER_HOST="ssh://user@192.168.1.100"
CONTAINER_NAME=zen_gates
FOLDER=/home/dockeruser/myfolder
HEX_CONFIG=$(printf {\"containerName\":\"/$CONTAINER_NAME\"} | od -A n -t x1 | tr -d '[\n\t ]')
code --folder-uri "vscode-remote://attached-container+$HEX_CONFIG$FOLDER"
