Append values to a variable in Perl using the .= operator

Home > Search

Let's say you have a variable that contains fruit.

$fruit = "banana apple orange grape";

 

The .= operator can be used to append values to the end of the variable. In this example, pineapple will be appended to the $fruit variable.

$fruit .= "pineapple";

 

After pineapple has been appended, the variable can be printed.

print $fruit;

 

The original values in the variable plus pineapple will be printed.

banana apple orange grape pineapple
