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 check whether the number is palindrome or not.
line 1: number
Print “palindrome” if the number is palindrome else print “not palindrome”
The following is the shell script to check whether the number is palindrome or not:
echo enter n read n num=0 on=$n while [ $n -gt 0 ] do num=$(expr $num \* 10) k=$(expr $n % 10) num=$(expr $num + $k) n=$(expr $n / 10) done if [ $num -eq $on ] then echo palindrome else echo not palindrome fi
$ enter n $ 121 $ palindrome
