A shell script is a computer program designed to be run by the Unix shell, a command-line interpreter. The various dialects of shell scripts are considered to be scripting languages. Typical operations performed by shell scripts include file manipulation, program execution, and printing text. A script that sets up the environment, runs the program, and does any necessary cleanup, logging, etc. is called a wrapper.
In this post, we will write a shell script to print all Prime Numbers Between n and m.
line 1: n and m
The following is the shell script to print all Prime Numbers Between n and m:
echo enter m and n read m n for a in $(seq $m $n) do k=0 for i in $(seq 2 $(expr $a - 1)) do if [ $(expr $a % $i) -eq 0 ] then k=1 break fi done if [ $k -eq 0 ] then echo $a fi done
$ enter m and n $ 3 10 $ 3 $ 5 $ 7
