My bashrc : Random Geekery

GNU Bash runs this for non-login shells. So if we aren’t running interactively, skip the rest of the file.

# If not running interactively, don't do anything
case $- in
    *i*) ;;
      *) return;;
esac

Manage the command history. Only include unique commands that don’t start with a space. Append to the history file so it grows over time, but don’t let it get too big.

HISTCONTROL=ignoreboth
shopt -s histappend
HISTSIZE=1000
HISTFILESIZE=2000

Check the window size after each command and update the values of LINES and COLUMNS.

shopt -s checkwinsize

I’m accustomed to ** meaning a recursive match in globs. Just making sure that carries over to interactive shell sessions.

shopt -s globstar

Track those shell aliases I’m so fond of assembling.

[ -f ~/.bash_aliases ] && . ~/.bash_aliases

Enable tab-completion features in case they weren’t already.

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

Add Homebrew completions when I’ve got that available.

if which brew &> /dev/null; then
  export BREW_PREFIX=`brew --prefix`
  if [ -f "$BREW_PREFIX/etc/bash_completion" ]; then
    . "$BREW_PREFIX/etc/bash_completion.d/git-completion.bash"
    . "$BREW_PREFIX/etc/bash_completion.d/git-prompt.sh"
    . "$BREW_PREFIX/etc/bash_completion"
  fi
fi

Run the keychain OpenSSH key manager for my shell sessions.

if which keychain > /dev/null; then
  eval `keychain --eval --agents ssh id_rsa`
fi

Load Direnv hooks if available.

if which direnv > /dev/null; then eval "$(direnv hook bash)"; fi

Load hooks for the fzf fuzzy finder.

[ -f ~/.fzf.bash ] && source ~/.fzf.bash

I sometimes have things to run locally that don’t need to be in my universal config.

[ -f ~/.bashrc_local_after ] && . ~/.bashrc_local_after

Try to get tmux playing nice with existing sessions.

if [[ -n "\$PS1" ]] && [[ -z "\$TMUX" ]] && [[ -n "\$SSH_CONNECTION" ]]; then
  tmux attach-session -t remote || tmux new-session -s remote
fi

And finally, show my pretty prompt from Starship.

eval "$(starship init bash)"
