What is the difference between my and local in Perl?

Question

I am seeing both of them used in this script I am trying to debug and the literature is just not clear. Can someone demystify this for me?

Answer 1

Look at the following code and its output to understand the difference.

our $name = "Abhishek";

sub sub1
{
    print "\nName = $name\n";
    local $name = "Abhijeet";

    &sub2;
    &sub3;
}

sub sub2
{
    print "\nName = $name\n";
}

sub sub3
{
    my $name = "Abhinav";
    print "\nName = $name\n";
}


&sub1;

Output is :

Name = Abhishek

Name = Abhijeet

Name = Abhinav
