Anyone ever write a unix clock program that display the clock out in 7 segment LCD style.

I tried doing one with case statements:

case $clock in
#This prints out the number 0
echo " -"
echo "| |"
echo "| |"
echo " -"

#This prints out the number 1
echo "|"
echo "|"

Etc, to the rest of the number 2-9.
But I want the clock to print out line by not number by number.(5 lines) All with "-" and "|".
Including military format, hours, minutes, seconds.
So I thought of doing some sort of for loop which would have to execute 6 times(2 for every set - hours,minutes,seconds)
I am really confused.

Not sure <I>why</I> you would want to do this, but anyway...

You could probably get clever with Ansi escape codes to move
the cursor around for you:


Puts the cursor at row <STRONG>R</STRONG> and column <STRONG>C</STRONG>

See <A HREF="http://www.linux.org/docs/ldp/howto/Bash-Prompt-HOWTO-6.html">http://www.linux.org/docs/ldp/howto/Bash-Prompt-HOWTO-6.html</A> for some more examples.

What I am trying to do is print out my time(date) line by line so if the time was 09 23 21
it would come out like(that's the first 2 lines) just to give you an idea.

I've tried using a for loop that excutes 6 times one for every number, then have another for loop that executes 5 times for the number of lines, then have case statements that echo the "-" or the "|" but I can't seem to get it going. I tried using 10 case statements 0-9 but I ain't getting anywhere.

You should use figlet for this:

Source code is available, if you like. There are webified versions if you dont feel like downloading and installing.
