~/.bashrc

If not running interactively, don't do anything

  [[ $- != *i* ]] && return

Bash Completion

  [ -r /usr/share/bash-completion/bash_completion ] && . /usr/share/bash-completion/bash_completion

FZF

  source /usr/share/fzf/key-bindings.bash

Ignore case for auto-completion

  bind "set completion-ignore-case on"
  bind "set show-all-if-ambiguous on"

Use Color

  use_color=true

Some config

  # Unset some variables
  unset use_color safe_term match_lhs sh

  # Allow local processes with root privileges to connect to the locally running X server
  xhost +local:root > /dev/null 2>&1

  # Autocomplete sudo commands
  complete -cf sudo

  # Line wrap on window resize
  shopt -s checkwinsize

  # Enable history expansion with space
  # E.g. typing !!<space> will replace the !! with your last command
  bind Space:magic-space

  # Expand Aliases
  shopt -s expand_aliases

  # Auto "cd" when entering just a path
  shopt -s autocd

  # Enable history appending instead of overwriting
  shopt -s histappend

  # Save multi-line commands as one command
  shopt -s cmdhist

Prompt - PS1

  export PS1="\[$(tput bold)\]\[$(tput setaf 1)\][\[$(tput setaf 3)\]\u\[$(tput setaf 2)\]@\[$(tput setaf 4)\]\h \[$(tput setaf 5)\]\W\[$(tput setaf 1)\]]\[$(tput setaf 7)\]\\$ \[$(tput sgr0)\]"

Rebind up and down arrow keys to search through bash history

  bind '"\e[A": history-search-backward'
  bind '"\e[B": history-search-forward'

Aliases

Better defaults for some commands

  alias ls='ls -hN --color=auto --group-directories-first'
  alias grep='grep --colour=auto'
  alias cp="cp -i"     # confirm before overwriting something
  alias df='df -h'     # human-readable sizes
  alias free='free -m' # show sizes in MB
  alias mutt="neomutt"
  alias tmux='tmux -f $XDG_CONFIG_HOME/tmux/tmux.conf'

One letter aliases

  alias r="ranger"
  alias t="tmux"
  alias v="nvim"
  alias sv='sudo -E nvim'
  alias g="git"
  alias m="neomutt"
  alias o="xdg-open"

Neovim

  command -v nvim >/dev/null && alias vim="nvim" vimdiff="nvim -d" # Use neovim for vim if present.

Vim-like

  alias :q=exit
  alias :e=nvim

Print each PATH entry on a separate line

  alias path='echo -e ${PATH//:/\\n}'

Functions

colors - Display colors

  colors() {
      local fgc bgc vals seq0

      printf "Color escapes are %s\n" '\e[${value};...;${value}m'
      printf "Values 30..37 are \e[33mforeground colors\e[m\n"
      printf "Values 40..47 are \e[43mbackground colors\e[m\n"
      printf "Value  1 gives a  \e[1mbold-faced look\e[m\n\n"

      # foreground colors
      for fgc in {30..37}; do
          # background colors
          for bgc in {40..47}; do
              fgc=${fgc#37} # white
              bgc=${bgc#40} # black

              vals="${fgc:+$fgc;}${bgc}"
              vals=${vals%%;}

              seq0="${vals:+\e[${vals}m}"
              printf "  %-9s" "${seq0:-(default)}"
              printf " ${seq0}TEXT\e[m"
              printf " \e[${vals:+${vals+$vals;}}1mBOLD\e[m"
          done
          echo; echo
      done
  }

tre - Tree display

tre is a shorthand for tree with hidden files and color enabled, ignoring the .git directory, listing directories first. The output gets piped into less with options to preserve color and line numbers, unless the output is small enough for one screen.

  function tre() {
      tree -aC -I '.git|node_modules|bower_components' --dirsfirst "$@" | less -FRNX;
  }

mkd - Create a new directory and enter it

  function mkd() {
      mkdir -p "$@" && cd "$_";
  }

fs - Filesize of directory

  function fs() {
      if du -b /dev/null > /dev/null 2>&1; then
          local arg=-sbh;
      else
          local arg=-sh;
      fi
      if [[ -n "$@" ]]; then
          du $arg -- "$@";
      else
          du $arg .[^.]* ./*;
      fi;
  }

nullify - Redirect both standard output and standard error, as well as sending to background

  function nullify() {
      "$@" >/dev/null 2>&1
  }

sms - Send SMS

https://doronbehar.com/articles/using-kdeconnect-to-comfortably-send-sms-messages-from-the-shell/#kdeconnects-builtin-sms-interface

  sms(){
      local args="$@"
      # local phone_number name phone_type
      # khard phone --parsable | sort -u | fzf | IFS=$'\t' read -r phone_number name phone_type
      local phone_number=$(khard phone --parsable | sort -u | fzf | cut -f1 -d$'\t')
      if [[ -z "${phone_number}" ]]; then
          echo No recipient was chosen >&2
          return
      else
          kdeconnect-cli --send-sms "${args}" --destination "${phone_number}" --device 4de3b5de2264a17c
      fi
  }

Bash History

Undocumented feature which sets the size to "unlimited". http://stackoverflow.com/questions/9457233/unlimited-bash-history

  # Huge history. Doesn't appear to slow things down, so why not?
  HISTSIZE=500000
  HISTFILESIZE=100000

  # Avoid duplicate entries
  HISTCONTROL="erasedups:ignoreboth"

  # Don't record some commands
  export HISTIGNORE="&:[ ]*:exit:ls:bg:fg:history:clear"

  # Use standard ISO 8601 timestamp
  # %F equivalent to %Y-%m-%d
  # %T equivalent to %H:%M:%S (24-hours format)
  HISTTIMEFORMAT='%F %T '

Change the file location because certain bash sessions truncate .bash_history file upon close. http://superuser.com/questions/575479/bash-history-truncated-to-500-lines-on-each-login

  export HISTFILE=~/.bash_eternal_history

Force prompt to write history after every command. http://superuser.com/questions/20900/bash-history-loss
