Debian/Ubuntu – Make SSH Terminal Run with Colors

For those who actually get used to have colors in SSH terminal session, will surely feels weird if you SSH into Debian/Ubuntu because by default, the terminal session will NOT run with color-enabled mode. It might be small issue but it will help you a lot in administrating and managing the Linux box when you can see and differentiate things with colors.

What you need to do is replace following content into /root/.bashrc or /home/any_user/.bashrc file (this is actually an extended version with some tweak for your .bashrc file to enable colors):

# ~/.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
# don't overwrite GNU Midnight Commander's setting of `ignorespace'.
HISTCONTROL=$HISTCONTROL${HISTCONTROL+:}ignoredups
# ... or force ignoredups and ignorespace
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)
 
# 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 "$(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
 
if [ -n "$force_color_prompt" ]; then
if [ -x /usr/bin/tput ] && tput setaf 1 >&/dev/null; then
# We have color support; assume it's compliant with Ecma-48
# (ISO/IEC-6429). (Lack of such support is extremely rare, and such
# a case would tend to support setf rather than setaf.)
color_prompt=yes
else
color_prompt=
fi
fi
 
if [ "$color_prompt" = yes ]; then
PS1='${debian_chroot:+($debian_chroot)}[33[01;32m][email protected][33[00m]:[33[01;34m]w[33[00m]$ '
else
PS1='${debian_chroot:+($debian_chroot)}[email protected]:w$ '
fi
unset color_prompt force_color_prompt
 
# If this is an xterm set the title to [email protected]:dir
case "$TERM" in
xterm*|rxvt*)
PS1="[e]0;${debian_chroot:+($debian_chroot)}[email protected]: wa]$PS1"
;;
*)
;;
esac
 
# 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'
 
#alias grep='grep --color=auto'
#alias fgrep='fgrep --color=auto'
#alias egrep='egrep --color=auto'
fi
 
# some more ls aliases
#alias ll='ls -l'
#alias la='ls -A'
#alias l='ls -CF'
 
# 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 [ -f /etc/bash_completion ] && ! shopt -oq posix; then
. /etc/bash_completion
fi
