boater

this script runs a docker container, mounts the current directory (or specified dir) as a volume, and opens a terminal in the container.

*this script requires docker

download the script and make it executable with:

curl -sL https://s76.co/get-boater -o ~/boat.sh && chmod +x ~/boat.sh

create an alias so you can run boat

echo "\nalias boat=~/boat.sh" >> ~/.bashrc && . ~/.bashrc 
# if you use zsh
echo "\nalias boat=~/boat.sh" >> ~/.zshrc && . ~/.zshrc

# check it worked
boat -h
