Exp. No. 4 Multiplication Table Shell Programming
Aim
To write simple shell scripts using shell programming fundamentals.
The activities of a shell are not restricted to command interpretation alone. The shell
also has rudimentary programming features. Shell programs are stored in a file (with
extension .sh). Shell programs run in interpretive mode. The original UNIX came with the
Bourne shell (sh) and it is universal even today. C shell (csh) and Korn shell (ksh) are also
widely used. Linux offers Bash shell (bash) as a superior alternative to Bourne shell.
G) Multiplication Table
Multiplication table – multable.sh
clear
echo -n "Which multiplication table? : "
read n
for x in 1 2 3 4 5 6 7 8 9 10
do
p=`expr $x \* $n`
echo -n "$n X $x = $p"
sleep 1
done
Output
$ sh multable.sh
Which multiplication table? : 6
6 X 1 = 6
6 X 2 = 12
