Hazel watches for any new PDFs with that string in the filename. When I scan a receipt in Scanbot, I have a snippet "wwr" that expands to "Work receipt".
I then have a series of rules set up to move the files based on their names. If the file hasn't been OCR'd already, a script will run to launch PDFPenPro and OCR the file. This folder is for files added from my Fujitsu ScanSnap or Scanbot for iOS. Be sure to add your own Pushover key and secret, or remove it if you don't need notifications. For the one week folder, I also get a notification the day before to remind me that it'll get deleted.
After the set amount of time, the files will be deleted and I'm sent a push notification. Files that I want to share temporarily are copied to that folder. I have two folders named "One day" and "One week".
If you have a Dropbox Pro account, this is now a feature built right in. I realize I could do this directly in IFTTT, but I don't like that you can't make the album private. My AppleTV is then set to that album so that we have an updated list of photos as a screen saver. Each time this file runs, I have a script that uploads the photo to a private Flickr album. I have a rule set up in IFTTT that will append to a text file each time my girlfriend or I post a photo to Instagram. Since my girlfriend runs her blog over at with the same static blog generator, it's much simpler for her to create a file just like this when she wants to publish her blog. If that file exists, the shell script is run and the file is then deleted. On iOS, it's not quite as easy and so I use Hazel to watch my blog folder for a file called 'publish.blog'. While I'm on my Mac, it's easy to run a shell script to publish my blog.
I use a static blog generator, Pelican, which means that I can store the entire project, including the Python code in my Dropbox account. Hazel looks at the metadata of the photos in Camera Uploads and if the photo was taken by the front camera and the app used to create the file was Camera+, it's moved to its own special folder and renamed to just YYYY-MM-DD. I've made sure to always use Camera+ to take these photos. I take a selfie every day (620 days and counting) and am far too lazy to move that photo to its own special photo every day. The only exception is that I add a "carousel" tag to these photos so that I know they were added from Carousel. I want these photos in my normal photos folder and so I run the same set of rules as my Camera Uploads to reorganize these photos. In this folder, more folders are created with the email address of the person who shared the photos with you. If you use Carousel and have ever saved photos that someone else shared with you, you'll know that a completely different folder is created in Dropbox called Carousel. I've written about this in more detail here. I move all of my photos into a photos folder organized by year. I love that Carousel will automatically upload my photos to Dropbox, but the Camera Uploads folder becomes a wasteland of files if you don't organize them on a regular basis. I've talked about this one a bit in the past. Hazel watches multiple folders in my Dropbox folder and keeps my Dropbox much more organized than I ever would manually. Hazel may be my favorite reason for having an always-on Mac. Nothing too fancy or special here, but it's a nice alternative to Time Machine as an offsite backup. Since I have so much space, I use it as an offsite backup for my laptop using Arq over sftp. My MacBook Air doesn't have enough space to store all my files and so the Mac Mini is the place where I store all my Dropbox files locally so that I can run workflows and have a local backup. All of my Dropbox files are synced to this computer.
