 **aperture** <sub>and funperture</sub>  
 A simple little script that echos one of two things. Either the aperture logo, or how the aperture logo got into the script. I like it.
 
+**backupBookstack.sh**  
+A script to back up a Bookstack instance (https://bookstackapp.com). I run it weekly. It works well enough for me to post it here so...
+
 **backupProgramFiles.sh**  
 This is a script that I created to zip up my Program Files folders on my C: drive as those are permanently excluded by the backup software I use. I could probably dive in and pick specific applications that I know store their configutaions in the Program Files folders but for now I just do the whole thing. This script also clears out backups older than 2 weeks (I run it weekly) and emails a summary to the provided address through the specified mail relay server. Be sure to edit smtp-creds.sh to include your information.
