How do I know if I can or should clean up anything? I have a ton of installed apps, and a brew update takes forever.

I'd like to at least find which apps I no longer use.

I did brew autoremove, one question here, and it found and removed a couple files, but no noticeable difference in brew update.

I can brew list, but so many of them are libraries, and there are so many of them, that I don't really want to do brew info app on each of them. Surely there's a way to tell the difference between apps that I installed vs libraries?

A Perl script to get Access times of the target of the links placed in /usr/local/bin. Then it shows the oldest-accessed files last.

But I don't know if this is the best answer, or if there's something that can be done in homebrew. I don't even know if this is necessary - is speeding up the upgrade process possible?

#!/usr/bin/perl
# Looking for old homebrew apps to get rid of

use strict;
use warnings;
use File::Spec;
use POSIX qw(strftime);


my $dir = '/usr/local/bin';


my @sorted_by_oldest_used =
    sort { $b->[2] <=> $a->[2] }
    map {
        my $t = readlink;
        $t = "$dir/$t" if not File::Spec->file_name_is_absolute($t);
        $t =~ /Cellar|Cask/ ? [ $_, $t, -A $t ] : ()
    }
    grep { -l }
    glob "$dir/*";


foreach my $res_ar (reverse @sorted_by_oldest_used) {
    my $date = strftime("%Y_%m_%d_%H:%M:%S", localtime(time - $res_ar->[2] * 24 * 60 * 60));
    printf "%s\t%s\n", $date, $res_ar->[0];
}

Code credit: Stackoverflow question I asked, with a better response than the script I came up with.
