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.

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

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
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"
