Critiques ??

As a general rule, avoid subroutine prototypes unless you have good reason for them. (See, e.g., Far More than Everything You've Ever Wanted to Know about Prototypes in Perl -- by Tom Christiansen.) With the prototype removed, and employing some Perl idioms, sub fexist can be simplified to:

sub fexist { for (glob $_[0]) { return 3 if -l; return 2 if -d; return 1 if -f; } return 0; }
Improvements ??

Since the aim is to cleanup unwanted files, perhaps it would be better to integrate sub fexist with the cleanup code? Something like this:

use v5.14; ... sub cleanup { for (glob $_[0]) { cleanup_link($_) when -l; cleanup_dir ($_) when -d; cleanup_file($_) when -f; } }

Hope that helps,
