Shell script find occurrence of any character

Question

How can I find if a pattern has occurred in a variable in if condition.

Eg:

var1="DEFABCTY"
var2="EFGH"

How can I use if in shell script to find which of the two variables has "ABC" using if statement.

This is quite simple and has been asked many times. What have you tried and what are you missing? — fedorqui

You can use pattern matching and variable indirection:

for var in var1 var2 ; do
    if [[ ${!var} = *ABC* ]] ; then
        echo ABC occurs in $var
    fi
done
