This will describe how to render coloured output in Unix Shells.

As you probably know PS1 is the shell variable that describes the output in front of your command line. I will demonstrate on this variable how it's done, because in our environment we are using it to display the most important variables on a system (e.g. Horc instance, User, ...)

Here is how to highlight them:

FBLUE="\0033[34;1m"
NOCOL="\0033[0m"
FGREEN="\0033[32;1m"
FRED="\0033[31;1m"

PS1=`echo $FRED`"$LOGNAME@$(hostname) "`echo $FBLUE`"Blue text"`echo $FGREEN`"$anothervariable"`echo $NOCOL`" \$PWD #"

Now, that's cool ;-)

of course you could also:

echo "\0033[34;1m" BlueText; echo "\0033[0m"
