I've looking over a script for work and I've had a problem with the script not listing the files in alphabetical order. To look up PIDs for apps, it would be beneficial to have them listed in that order. Here is what I've been reviewing.

hash::util
Hash::Util(3pm) Perl Programmers Reference Guide Hash::Util(3pm)NAME
Hash::Util - A selection of general-utility hash subroutines
SYNOPSIS
use Hash::Util qw(lock_keys unlock_keys
lock_value unlock_value
lock_hash unlock_hash);
%hash = (foo => 42, bar => 23);
lock_keys(%hash);
lock_keys(%hash, @keyset);
unlock_keys(%hash);
lock_value (%hash, 'foo');
unlock_value(%hash, 'foo');
lock_hash (%hash);
unlock_hash(%hash);
DESCRIPTION
"Hash::Util" contains special functions for manipulating hashes that don't really warrant a keyword.
By default "Hash::Util" does not export anything.
Restricted hashes
5.8.0 introduces the ability to restrict a hash to a certain set of keys. No keys outside of this set can be added. It also introduces
the ability to lock an individual key so it cannot be deleted and the value cannot be changed.
This is intended to largely replace the deprecated pseudo-hashes.
lock_keys
unlock_keys
lock_keys(%hash);
lock_keys(%hash, @keys);
Restricts the given %hash's set of keys to @keys. If @keys is not given it restricts it to its current keyset. No more keys can be
added. delete() and exists() will still work, but will not alter the set of allowed keys. Note: the current implementation prevents the
hash from being bless()ed while it is in a locked state. Any attempt to do so will raise an exception. Of course you can still bless()
the hash before you call lock_keys() so this shouldn't be a problem.
unlock_keys(%hash);
Removes the restriction on the %hash's keyset.
lock_value
unlock_value
lock_value (%hash, $key);
unlock_value(%hash, $key);
Locks and unlocks an individual key of a hash. The value of a locked key cannot be changed.
%hash must have already been locked for this to have useful effect.
lock_hash
unlock_hash
lock_hash(%hash);
lock_hash() locks an entire hash, making all keys and values readonly. No value can be changed, no keys can be added or deleted.
unlock_hash(%hash);
unlock_hash() does the opposite of lock_hash(). All keys and values are made read/write. All values can be changed and keys can be
added and deleted.
