UNIX for Dummies Questions & Answers

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

I tried doing one with case statements:

!/usr/bin/ksh
clock=`date`
case $clock in
#This prints out the number 0
0)
echo " -"
echo "| |"
echo
echo "| |"
echo " -"
;;

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

Thanks,

A

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:

echo "\033[<STRONG>R</STRONG>;<STRONG>C</STRONG>H"

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.

Thanks,

You should use figlet for this:
http://st-www.cs.uiuc.edu/users/chai/figlet.html

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

Code:

 _     ___         ___   ___         ___   ___  
  |       |   |       | |  /|   |   |  /| |   | 
  +    -+-         -+-  | + |       | + |  -+-| 
  |   |       |   |     |/  |   |   |/  |     | 
 ---   ---         ---   ---         ---   ---

Thanks again,
but I need something hand coded and strictly in unix(bash)
scripting.
I am looking at this as an example but I'm getting the same
as I already have.
