Colourful boot messages

The functions used for the status messages upon boot are defined in /lib/lsb/init-functions and may be overwritten in /etc/lsb-base-logging.sh.

To add colours, in that init-functions file find the function log_use_fancy_output() and below the fi add the lines

{% highlight bash %}

… else FANCYTTY=0 fi

BEGIN --- colour definition

if [ -n "$TERM" ]; then NORMAL=$TPUT sgr0 BOLD=$TPUT bold BLINK=$TPUT blink BLACK=$TPUT setaf 0 RED=$TPUT setaf 1 GREEN=$TPUT setaf 2 YELLOW=$TPUT setaf 3 BLUE=$TPUT setaf 4 MAGENTA=$TPUT setaf 5 CYAN=$TPUT setaf 6 WHITE=$TPUT setaf 7 fi

END --- colour definition

case "$FANCYTTY" in 1|Y|yes|true) true;; …

{% endhighlight %}

After that, edit the lsb-base-logging.sh and change e.g. the output of log_end_msg():

{% highlight bash %} 
…
if [ "$COL" ] && [ -x "$TPUT" ]; then
    printf "\r"
    $TPUT hpa $COL
    if [ "$1" -eq 0 ]; then
        echo "${BOLD}${BLUE}[${GREEN} OK ${BLUE}]${NORMAL}"
    else
        echo "${BOLD}${BLUE}[${RED}fail${BLUE}]${NORMAL}"
    fi
else
…
{% endhighlight %}

Your next boot will look like this:
