How to check multiple conditons in a IF statement

Question

I am trying to test for multiple conditions in the following if statement:

If [[[ "$var1" = "$var2" || "$var1" = "$var3" || "$var1" = "$var4" ]]];

However, when I execute the above mentioned syntax I am getting an error. Can anyone help me in getting multiple conditions checking in IF statement?

Solution 1

You have too many brackets, and the if should not be capitalized. Try like this:

if [[ "$var1" == "$var2" || "$var1" == "$var3" || "$var1" == "$var4" ]]; then

Solution 2

Might be easier to use the standard sh syntax rather than that (mispelled, it should be [[ instead of [[[) ksh construct:

case $var1 in
  "$var2" | "$var3" | "$var4") echo match;;
  *) echo no match;;
