I found this code on some script :

*test = \&show;

What is "*" means? Isn't that reference/pointer is using "\" symbol?

Read the Typeglobs and Filehandles section of the 'perldata' file
for details.

*foo is a typeglob. It's a way of representing everything named "foo":
the scalar $foo, the array [at] foo, the hash %foo, the subroutine &foo, the
filehandle foo, the dirhandle foo, the format name foo...

Assigning a reference to a typeglob means that the particular compartment
of the glob (in the case above, the function compartment of the glob) is
an alias to that which was referred to.

*test = \&show;

means that &test is an alias for &show -- calling the test() function is
the same as calling the show() function.

For more on typeglobs, see 'perldoc perldata'.
