RE: What is -> Symbol in perl

This is called symbolik link.

ex: ROSE-> FLOWER.

That is wen we want to read ROSE file in Hard disk it will direct it to FLOWER file.

Though we thought of reading ROSE file...We will be ending up reading the content of Flower file.

RE: What is -> Symbol in perl

Arrow operator -> is used for deferencing references to array or hash.

$arr ['1' '2' '3' '4'];

To retrive the value of first element :
$val $arr->[1];
Now variable $var will contain '2'.
