Yes, if no_chdir is not set, then
$_ is the current file's name with no path
$File::Find::name is the current file's name with the path
$File::Find::dir is the path to the current file
You may want to read the [perldoc File::Find][0].

The callback is printing the value of $File::Find::name (which, again,
is set by the File::Find::find function before the callback is
called).
[Jatin] Chas , when you say that the File::Find's find method sets its
name variable before the callback is called , Do you mean that this
"name"

$File::Find::name is a fully-qualified variable, just in case you're

[Jatin] No , i act
File::Find's interface is through its package variables.
[Jatin] So my subroutine that i use with the File::Find's find method
has access to the package variables ? Correct me if i am wrong.
It is a very
bad design and is much regretted, but there is nothing to do about it
now.

Yes, all types of references
Hi Jatin,
A callback is a reference to a subroutine.
[Jatin] if a callback is a reference to a subroutine then it can be
stored in scalar variable to call that subroutine. Am i correct in my
understanding ?
This reference when passed around,
allows other code to invoke it.
