Reposting from an email I sent a while back:
As several people have asked about my todo list within the last 2 weeks, I thought I’d share the goodness with everyone.
I’ve been using todo.txt for about a year now. http://todotxt.com/
Don’t let the website fool you. todo.txt isn’t (primarily) a gui app, or a phone app. The todo list is in a plain text file. There’s a dozen different tools that you can use to manage it, but I just use the command line:
t ls – what’s in my list?
t add ITEM – Adds ITEM to my todo list
t pri ## A – Makes item ## priority A
t do ## – Marks item ## as done, moves it to DONE list for later reference
t ls blarg – Lists todo items that match ‘blarg’
t lsp A – Show me all the things that are priority A
done – An alias to ‘cat ~/Dropbox/todo/done.txt’ which shows me what I’ve done most recently
If you happen to store your todo list in your Dropbox directory, you can then also use the free Android app to manage your todo list from your phone. (I’ve heard it also work with google drive, or owncloud, or a variety of other things.)
As someone who has used every possible todo list out there, including a dozen issue trackers, and writing a few different todo list webapps, sticking with a single tool for a whole year is unprecedented. Being able to work from the command line made all the difference for me, since that’s where I always am anyways.
