Nice series, though I don't know how many of us are using zsh. I'm sure many of us are struggling with a large and growing pile of digital photos. I generally batch rename based on exif info and file the pics into directories based on date before archiving. My issue is tagging. I'd like to know which pictures 'Bob' and 'Carol' are in, or which pictures were taken in Italy, or which pictures were from my son's birthday party. This is where I see a DB coming in handy. A flat file is also fine, perhaps one in each directory containing a line for each photo consisting of the filename followed by a set of tags or keywords. If I want to find the pics with 'Bob' in them, just iterate through the directories, grep through the tag file in each, and output the filenames that match. Certainly not as quick as a DB, but easy to maintain. I can see this growing into a nice little set of scripts that run reports and tell you which pictures have yet to be tagged, generates a list of currently used tags and their frequencies, etc. It'd be cool to be able to put a copy of all the photos I've taken of my sister in law on a Sunday between 1pm and 3pm into a directory with one command. Actually going through my entire collection and creating this tag DB is another story. »
