I have the following script to check for multiple condition occurred.
Script:
#!/bin/bash
echo "1.Add, 2.Sub, 3.Mul, 4.Div"
echo "Enter your choice:"
read ch
#Here i want to check the condition for 1, 01 and also 001
if [ $ch = 1 ]
then
echo "Addition goes here"
...
...
fi
Note: How can i use multiple condition using IN?
Like:
if [ $ch IN ('1','01','001') ]
Use a case statement instead:
case $ch in
1|01|001)
echo "Addition goes here"
;;
...
*)
echo "Invalid input"
esac
With bash, you can write:
if [[ $ch == @(1|01|001) ]]
Inside [[ ... ]], the == operator does pattern matching, and the extended pattern @(pattern-list) matches one or more of the given pattern.
