Using colors in Korn Shell

Here are some color codes you can use in the Korn Shell: 

## Reset to normal: \033[0m
NORM="\033[0m"

## Colors:
BLACK="\033[0;30m"
GRAY="\033[1;30m"
RED="\033[0;31m"
LRED="\033[1;31m"
GREEN="\033[0;32m"
LGREEN="\033[1;32m"
YELLOW="\033[0;33m"
LYELLOW="\033[1;33m"
BLUE="\033[0;34m"
LBLUE="\033[1;34m"
PURPLE="\033[0;35m"
PINK="\033[1;35m"
CYAN="\033[0;36m"
LCYAN="\033[1;36m"
LGRAY="\033[0;37m"
WHITE="\033[1;37m"

## Backgrounds
BLACKB="\033[0;40m"
REDB="\033[0;41m"
GREENB="\033[0;42m"
YELLOWB="\033[0;43m"
BLUEB="\033[0;44m"
PURPLEB="\033[0;45m"
CYANB="\033[0;46m"
GREYB="\033[0;47m"

## Attributes:
UNDERLINE="\033[4m"
BOLD="\033[1m"
INVERT="\033[7m"

## Cursor movements
CUR_UP="\033[1A"
CUR_DN="\033[1B"
CUR_LEFT="\033[1D"
CUR_RIGHT="\033[1C"

## Start of display (top left)
SOD="\033[1;1f"
Just copy everyting above and paste it into your shell or in a script. Then, you can use the defined variables: 
## Example - Red underlined
echo "${RED}${UNDERLINE}This is a test!${NORM}"

## Example - different colors
echo "${RED}This ${YELLOW}is ${LBLUE}a ${INVERT}test!${NORM}"

## Example - cursor movement
# echo " ${CUR_LEFT}Test"

## Create a rotating thingy
while true ; do
printf "${CUR_LEFT}/"
perl -e "use Time::HiRes qw(usleep); usleep(100000)"
printf "${CUR_LEFT}-"
perl -e "use Time::HiRes qw(usleep); usleep(100000)"
printf "${CUR_LEFT}\\"
perl -e "use Time::HiRes qw(usleep); usleep(100000)"
printf "${CUR_LEFT}|"
perl -e "use Time::HiRes qw(usleep); usleep(100000)"
done
Note that the perl command used above will cause a sleep of 0.1 seconds. Perl is used here, because the sleep command can't be used to sleep less than 1 second.
