Copy&Pasta CLI installations & config

homebrew - add to path

echo 'export PATH=$PATH:/home/linuxbrew/.linuxbrew/bin/' >> ~/.bashrc && source ~/.bashrc && brew help

docker - on debian

You cannot use linuxbrew to install docker engine. SO you need to install it manually. Brew can however be used to install docker cli with bashcompletion.

# install docker 
## you may want to check the script before running it
## source: https://docs.docker.com/engine/install/debian/#install-using-the-convenience-script
curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

# allow current user to manage docker
## source: https://docs.docker.com/engine/install/debian/#install-using-the-convenience-script
sudo groupadd docker
sudo usermod -aG docker $USER
## log out current user
docker run hello-world

bash completion

any binary installed with brew

If the binary is installed with brew there is a chance that the bash completion script is genereted to the $(brew --prefix)/etc/bash_completion.d/ direcoty. If so brew will tell you at the end of the installation.

# run once after installing brew
echo 'for BREW_COMPLETION in "$(brew --prefix)/etc/bash_completion.d/"*; do 
    [[ -r "$BREW_COMPLETION" ]] && source "$BREW_COMPLETION" 
done' \
>>~/.bashrc && source ~/.bashrc

# after brew added a new completion script just source 
source ~/.bashrc
