Custom ~/.bashrc

Nichts ist wichtiger als ein Backup der Config-Dateien. Eine der wichtigsten ist die ~/.bashrc. Immerwieder verfeinert und auf die eigenen Ansprüche angepasst wächst sie über Jahre hinweg mit. Diese zu verlieren ist mehr als ärgerlich. Darum hier meine persönliche .bashrc zur Anpassung der Konsole unter Linux mit Kommentaren:

# ~/.bashrc: executed by bash(1) for non-login shells.
# see /usr/share/doc/bash/examples/startup-files (in the package bash-doc)
# for examples

# If not running interactively, don't do anything
[ -z "$PS1" ] && return

# don't put duplicate lines in the history. See bash(1) for more options
#export HISTCONTROL=ignoredups

# check the window size after each command and, if necessary,
# update the values of LINES and COLUMNS.
shopt -s checkwinsize

# make less more friendly for non-text input files, see lesspipe(1)
[ -x /usr/bin/lesspipe ] && eval "$(lesspipe)"

# set variable identifying the chroot you work in (used in the prompt below)
if [ -z "$debian_chroot" -a -r /etc/debian_chroot ]; then
   debian_chroot=$(cat /etc/debian_chroot)

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
   PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '
   PS1='${debian_chroot:+($debian_chroot)}\u@\h:\w\$ '

# Comment in the above and uncomment this below for a color prompt
#PS1='${debian_chroot:+($debian_chroot)}\[\033[01;32m\]\u@\h\[\033[00m\]:\[\033[01;34m\]\w\[\033[00m\]\$ '

# If this is an xterm set the title to user@host:dir
case "$TERM" in
   PROMPT_COMMAND='echo -ne "\033]0;${USER}@${HOSTNAME}: ${PWD/$HOME/~}\007"'

# 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

# enable color support of ls and also add handy aliases
if [ "$TERM" != "dumb" ]; then
   eval "`dircolors -b`"
   alias ls='ls --color=auto'
   #alias dir='ls --color=auto --format=vertical'
   #alias vdir='ls --color=auto --format=long'

# some more ls aliases
alias ll='ls -hl'
alias la='ls -A'
alias lh='ls -hal'
#alias l='ls -CF'

# 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 [ -f /etc/bash_completion ]; then
#    . /etc/bash_completion
