ncurses

There are Perl modules, C libraries, and C++ libraries for this.

I'd recommend you get a book though, it's tricky at best.

Caesar - I know what you mean. I too wish that HP-UX would use colors (like linux does).

The best I can tell you is how to highlight a string of text.

at the beginning of your script put these two lines:

BOLD="`tput smso`"
NORMAL="`tput rmso`"

Then to make something bold (highlighted) do it like this:

echo "${BOLD}bla bla bla${NORMAL}"

and "bla bla bla" will be highlighted.

Hi Caesar:

I think that the best you can do is bold or blink. Check this out:

man terminfo

The tput command can generate a terminal-specific escape sequence for any of the features listed for the terminfo database entry of that terminal. To see what is defined for the current terminal:

untic $TERM

In all cases, $TERM must match the terminal you are using. If your profile sets $TERM using ttytype, then the untic command will show the features available for that terminal. Decode the untic entries using the man page for terminfo (which defines the curses library calls).

here are some example tputs to set colors.

# sets parameters for highlighting or colorizing text
bold="$(tput smso 2>/dev/null)"
undl="$(tput smul 2>/dev/null)"
norm="$(tput rmso 2>/dev/null)"

bla="$(tput setaf 0 2>/dev/null)"
red="$(tput setaf 1 2>/dev/null)"
gre="$(tput setaf 2 2>/dev/null)"
yel="$(tput setaf 3 2>/dev/null)"
blu="$(tput setaf 4 2>/dev/null)"
pur="$(tput setaf 5 2>/dev/null)"
cya="$(tput setaf 6 2>/dev/null)"
whi="$(tput setaf 7 2>/dev/null)"

off="$(tput sgr0 2>/dev/null)"
HI="$(tput smso 2>/dev/null)"
LO="$(tput sgr0 2>/dev/null)"

but as bill pointed out, these are terminal specific esacape sequences. and xterm doesn't have any. these will work for a dtterm. you'll have to test what capabilities the terminal has and set values appropriately. such as for an xterm you could use bold for yellow and bold inverse for red and underline for blue, etc. This way if someone is using an xterm there is some differentiation in the visual presentation albeit not colors. and if someone is using an dtterm their visual presentation would be differentiated by colors.
