Bash setup

Bash aliases

Create the file storing your aliases

touch ~/.bash_aliases

Include this file in your ~/.bashrc file

if [ -e $HOME/.bash_aliases ]; then
    source $HOME/.bash_aliases
fi

`.bash_aliases` file

alias hg='echo "Use !\$CMD_HISTORY_NUM to run the specific cmd" && history|grep'
alias ls='ls -GFh'
alias ll='ls -lah'
alias gitcred='git config credential.helper store'
alias gitcredunset='git config --unset credential.helper store'
alias gitbranchclean='git branch | grep -E -v "master|main" | xargs -n 1 git branch -d'
alias update='sudo apt-get update && sudo apt-get upgrade -y'
alias tmp='rm -rf tmp/ && mkdir tmp && cd tmp/'

gitclonecd() {
  git clone "$1" && cd "$(basename "$1" .git)"
}

Setup a personal folder to store binaries

Create a bin folder in your home folder:

mkdir -p $HOME/bin

Add the bin folder to your PATH:

if [ -d $HOME/bin ]; then
  export PATH="$HOME/bin:$PATH"
fi

From now, all the binaries that you will put in your bin folders will be accessible from anywhere in your system.

Bash autocompletion

A list of commande to enable autocompletion for things I use everyday:

echo "complete -C '$(which aws_completer)' aws" >> ~/.bashrc
echo "source <(kubectl completion bash)" >> ~/.bashrc
echo "source <(helm completion bash)" >> ~/.bashrc
echo "source <(minikube completion bash)" >> ~/.bashrc
echo "source <(skaffold completion bash)" >> ~/.bashrc
terraform -install-autocomplete
vault -autocomplete-install

Choosing which bash

Check which shells are installed:

cat /etc/shells

Switch to bash:

chsh -s /bin/bash

`~/.bashrc`

Add the following to your ~/.bashrc file:

# Turn on parallel history
shopt -s histappend
history -a

# enable programmable completion features (you don't need to enable
# this, if it's already enabled in /etc/bash.bashrc and /etc/profile
# sources /etc/bash.bashrc).
if ! shopt -oq posix; then
  if [ -f /usr/share/bash-completion/bash_completion ]; then
    . /usr/share/bash-completion/bash_completion
  elif [ -f /etc/bash_completion ]; then
    . /etc/bash_completion
  fi
fi

# Bash prompt
git_branch() {
  git branch 2> /dev/null | sed -e '/^[^*]/d' -e 's/* \(.*\)/(\1)/'
}
