Bash program to check if the Number is a Prime or not
Bash also known as GNU bash is a command language and unix shell script is a command line interpreter for operating system. It was designed by Brian Fox and was a free software which replaced Bourne shell. It first released in 1989 and some became go to for login shell for linux based operating systems like macOS, Linux based softwares, etc.
Prime number is a number that has only two factors i.e. the number itself and 1. For example, 2 , 3 , 5, 7 , 11 , 13 , 17 , 19 , 23 , 29….
Here we are given a number, and we need to find whether the given number is prime or not.
Input : A number Output : “The number is prime ” OR “The number is not prime” based on the number.
Example −
Input : 23 Output : The number is prime
ALGORITHM
Step 1 − Loop from 2 to n/2, i as loop variable
Step 2 − if number is divisible, print “The number is not prime” and flag = 1;
Step 3 − if flag != 1, then print “The number is prime”.
Step 4 − Exit.
PROGRAM
number=53 i=2 flag=0 while test $i -le `expr $number / 2` do if test `expr $number % $i` -eq 0 then flag=1 fi i=`expr $i + 1` done if test $flag -eq 1 then echo "The number is Not Prime" else echo "The number is Prime" Fi
OUTPUT
The number is Prime
