grnl is a simple clone of jrnl.
Journals aren't only for 13-year old girls and people who have too much time on their summer vacation. A journal helps you to keep track of the things you get done and how you did them. Your imagination may be limitless, but your memory isn't. For personal use, make it a good habit to write at least 20 words a day. Just to reflect what made this day special, why you haven't wasted it. For professional use, consider a text-based journal to be the perfect complement to your GTD todo list - a documentation of what and how you've done it.
to make a new entry, just type
grnl yesterday: Called in sick. Used the time to clean the house and spent 4h on writing my book.
and hit return. yesterday: will be interpreted as a timestamp. Everything until the first sentence mark (.?!) will be interpreted as the title, the rest as the body. In your journal file, the result will look like this:
2012-03-29 09:00 Called in sick.
Used the time to clean the house and spent 4h on writing my book.
If you just call grnl, you will be prompted to compose your entry - but you can also configure grnl to use your external editor.
