Cute script for sorting files, optionally can tell you about it, too.
Scans one directory, uses mapping regex calls, applies some subroutines optionally, checks another directory, and makes sure they are "in sync". It does this for a list of folders / regex maps provide in some file.
I use this on my Plex server setup to sort new files I dump to the ingest folder automatically based on the rules laid out in the YAML config file.
$ perl fairu-chan your-config.yml run
If you omit "run" it will just tell you what it would do, but won't do it (useful). You can also swap "run" for "daemon" and it'll check this stuff every so often automatically.
When you build the config file, if you want to make use of capture groups for the output you NEED to use named captured groups like (?<a_something>\d\d) or (?<b_thing> - \S+). These get lexically sorted and put into sprintf() for ease of use.
If you want Discord support include the "notification" section as shown in the example config, otherwise don't include it in the config at all. You'll need to install the WebService::Discord::Webhook, IO::Socket::SSL, and Data::Validate::URI Perl modules to use it. I will likely add other notification types if I desire them...
Also, if you want the config to automatically reload while in daemon mode when it's changed, you can include the "autoreload" variable and set it to true as shown in the example config. You'll need to install the File::Monitor module to use it. If re-parsing the config fails (either with signals or autoreload) then it'll just keep the old config.
SIGTERMwill gracefully exit after current sleep or operation finishes.SIGUSR1run a check as soon as the next sleep is finished instead of waiting for the full idle timeout.SIGUSR2try to parse the config again, if it fails keep the current, otherwise update to the new one.SIGINTwill just kill it where ever it is, no grace.
Perl, duh! I live like it's 1993.
