Colored Prompt in KornShell

view full story

http://unix.stackexchange.com – According to this StackOverflow post, it is possible have a colored prompt in KornShell. I have not been able to figure out how to do this. I am able to use color: echo -e "\033[34mLinux\033[00m" gives a blue "Linux" output, as does: printf "\033[34mLinux\033[00m" However, when I incorporate the escape codes into my PS1 prompt variable, they are not being escaped. What do I need to do to get a colored prompt? Besides being something of a sucker for eyecandy, I find that a colored prompt is useful when visually parsing output. (HowTos)
