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
… 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 "$FANCYTTY" in 1|Y|yes|true) true;; …
{% endhighlight %}After that, edit the lsb-base-logging.sh
and change e.g. the output of log_end_msg():
…
if [ "$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:
