Shell script to Calculate the bitwise binary calculation AND,OR and XOR for a Input String

Detailed Video Explanation is Below of the Script

Script

#!/bin/bash

#set -x

#############################################

#taking string from user#

echo "Please enter a string with binary calculation"

read v_str

#####Now check the string length is odd or even########

v_str_len=`echo ${#v_str}`

####check if the lenght is odd or even###########

if [ ! -z $v_str ]

then

if [ $((v_str_len%2)) -eq 0 ]

then

echo "lenght is even."

echo "exiting"

exit 1;

else

echo "Number is odd."

echo "Moving Ahead"

else

echo "Empty string passed"

echo "exiting Bye!!"

exit 1;

while [ ${#v_str} -gt 1 ]

if [ "$v_char2" = "A" ]

then

elif [ "$v_char2" = "B" ]

then

elif [ "$v_char2" = "C" ]

then

else

echo "wrong operator[use A of AND , B for OR,C for XOR]"

exit 1;

v_str=${v_str%$v_last3}${z}

done

echo "Result is $z"
