for examples
If not running interactively, don't do anything
case $- in *i*) ;; *) return;; esac
don't put duplicate lines or lines starting with space in the history.
See bash(1) for more options
HISTCONTROL=ignoreboth
append to the history file, don't overwrite it
shopt -s histappend
for setting history length see HISTSIZE and HISTFILESIZE in bash(1)
HISTSIZE=1000 HISTFILESIZE=2000
check the window size after each command and, if necessary,
update the values of LINES and COLUMNS.
shopt -s checkwinsize
If set, the pattern "**" used in a pathname expansion context will
match all files and zero or more directories and subdirectories.
#shopt -s globstar
make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(SHELL=/bin/sh lesspipe)"
set variable identifying the chroot you work in (used in the prompt below)
if [ -z "${debian_chroot:-}" ] && [ -r /etc/debian_chroot ]; then debian_chroot=$(cat /etc/debian_chroot) fi
set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in xterm-color) color_prompt=yes;; esac
uncomment for a colored prompt, if the terminal has the capability; turned
off by default to not distract the user: the focus in a terminal window
should be on the output of commands, not on the prompt
#force_color_prompt=yes

enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dircolors -b)" alias ls='ls --color=auto' #alias dir='dir --color=auto' #alias vdir='vdir --color=auto'

colored GCC warnings and errors
#export GCC_COLORS='error=01;31:warning=01;35:note=01;36:caret=01;32:locus=01:quote=01'
some more ls aliases
alias ll='ls -alF' alias la='ls -A' alias l='ls -CF'
Add an "alert" alias for long running commands. Use like so:
sleep 10; alert
alias alert='notify-send --urgency=low -i "$([ $? = 0 ] && echo terminal || echo error)" "$(history|tail -n1|sed -e '\''s/^\s*[0-9]\+\s*//;s/[;&|]\s*alert$//'\'')"'
Alias definitions.
You may want to put all your additions into a separate file like
~/.bash_aliases, instead of adding them here directly.
See /usr/share/doc/bash-doc/examples in the bash-doc package.
if [ -f ~/.bash_aliases ]; then . ~/.bash_aliases fi
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
