I've converted all of my documents to Adobe's ubiquitous PDF format. This includes everything I've ever written for pleasure or for school (excluding code of course). I was quite disappointed to find out that there was no way for me to do the conversions from a shell. I don't understand why Acrobat doesn't offer the ability to be run from the command-line. When the idea first came to me about converting everything to PDF I immediately thought about writing a simple, recursive shell script to go through my archival directories and convert all documents that hadn't been modified in the last year to PDF. Obviously, without the ability to do it this way, I was left to do each document individually. Though the process was relatively painless, it could have been much faster had a non-GUI option been available.
