Bashrc

What does that do?

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

Bash Completion

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

Ignore case for autocompletion

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

Use Color

use_color=true
alias ls='ls -hN --color=auto --group-directories-first'
alias grep='grep --colour=auto'

Set colorful PS1 only on colorful terminals.

dircolors –print-database uses its own built-in database instead of using /etc/DIR_COLORS. Try to use the external file first to take advantage of user additions. Use internal bash globbing instead of external grep binary.

safe_term=${TERM//[^[:alnum:]]/?}   # sanitize TERM
match_lhs=""
[[ -f ~/.dir_colors   ]] && match_lhs="${match_lhs}$(<~/.dir_colors)"
[[ -f /etc/DIR_COLORS ]] && match_lhs="${match_lhs}$(</etc/DIR_COLORS)"
[[ -z ${match_lhs}    ]] \
  && type -P dircolors >/dev/null \
  && match_lhs=$(dircolors --print-database)
[[ $'\n'${match_lhs} == *$'\n'"TERM "${safe_term}* ]] && use_color=true

if ${use_color} ; then
  # Enable colors for ls, etc.  Prefer ~/.dir_colors #64489
  if type -P dircolors >/dev/null ; then
    if [[ -f ~/.dir_colors ]] ; then
      eval $(dircolors -b ~/.dir_colors)
    elif [[ -f /etc/DIR_COLORS ]] ; then
      eval $(dircolors -b /etc/DIR_COLORS)
    fi
  fi

  if [[ ${EUID} == 0 ]] ; then
    PS1='\[\033[01;31m\][\h\[\033[01;36m\] \W\[\033[01;31m\]]\$\[\033[00m\] '
  else
    PS1='\[\033[01;32m\][\u@\h\[\033[01;37m\] \W\[\033[01;32m\]]\$\[\033[00m\] '
  fi
else
  if [[ ${EUID} == 0 ]] ; then
    # show root@ when we don't have colors
    PS1='\u@\h \W \$ '
  else
    PS1='\u@\h \w \$ '
  fi
fi

Some config

unset use_color safe_term match_lhs sh

xhost +local:root > /dev/null 2>&1

complete -cf sudo

# Line wrap on window resize
shopt -s checkwinsize

shopt -s expand_aliases

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

# Enable history appending instead of overwriting
shopt -s histappend

Prompt

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

SSH Agent

# if ! pgrep -u "$USER" ssh-agent > /dev/null; then
#     ssh-agent > "$XDG_RUNTIME_DIR/ssh-agent.env"
# fi
# if [[ ! "$SSH_AUTH_SOCK" ]]; then
#     eval "$(<"$XDG_RUNTIME_DIR/ssh-agent.env")"

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 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 y="yadm"
alias o="xdg-open"
alias x="sxiv -ft *"

Neovim

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

Magit

# alias magit="emacsclient -create-frame --alternate-editor=\"\" --eval '(magit-status)'"
alias magit="nvim -c MagitOnly"

Vim-like

alias :q=exit
alias :e=nvim

Print each PATH entry on a separate line

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

Functions

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
}

Meteo

meteo() {
  if [ -n "$*" ]; then
    address="wttr.in/"
    address+=$*
    address+="?lang=fr"
    curl "$address"
  else
    address="wttr.in/"
    address+="?lang=fr"
    curl "$address"
  fi
}
alias meteo=meteo

Upload using transfer.sh

upload() {
  # write to output to tmpfile because of progress bar
  tmpfile=$(mktemp -t transferXXX)
  # basefile=$(basename "$1" | sed -e 's/[^a-zA-Z0-9]/-/g')
  curl --progress-bar --upload-file "$1" "https://transfer.sh/" >> $tmpfile;
  cat $tmpfile | xsel -ib;
  echo "Copied:" $(cat $tmpfile);
  rm -f $tmpfile;
}
alias upload=upload

Extract archive

usage: ex <file>

ex ()
{
  if [ -f $1 ] ; then
    case $1 in
      *.tar.bz2)   tar xjf $1   ;;
      *.tar.gz)    tar xzf $1   ;;
      *.bz2)       bunzip2 $1   ;;
      *.rar)       unrar x $1     ;;
      *.gz)        gunzip $1    ;;
      *.tar)       tar xf $1    ;;
      *.tbz2)      tar xjf $1   ;;
      *.tgz)       tar xzf $1   ;;
      *.zip)       unzip $1     ;;
      *.Z)         uncompress $1;;
      *.7z)        7z x $1      ;;
      *)           echo "'$1' cannot be extracted via ex()" ;;
    esac
  else
    echo "'$1' is not a valid file"
  fi
}

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;
}

Create a new directory and enter it

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

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;
}

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

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

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 "${phone_number}" ]]; then
        echo No recipient was chosen >&2
        return
    else
        # echo "${name}"$'\t'"${phone_number}"$'\t'"${phone_type}" > ${_KDECONNECT_SMS_LAST_RECIPIENT}
        kdeconnect-cli --send-sms "${args}" --destination "${phone_number}" --device 4de3b5de2264a17c
        # kdeconnect-cli --device ${_KDECONNECT_DEFAULT_DEVICE} --send-sms "${args}" --destination "${phone_number}" && \
        # echo sent sms message to ${name} | fribidi
    fi
}

Bash History

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

export HISTFILESIZE=
export HISTSIZE=
export 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

PROMPT_COMMAND="history -a; $PROMPT_COMMAND"

Starship Prompt

eval "$(starship init bash)"
