I use a script that I got from http://www.marcelgagne.com/daily_journal.html. It works very well as long as you remember that *nix is case sensitive. I had to redo the script after reinstalling my computer and had some trouble getting the script to work. It ended up that I had spelled Journal with a capital J in the script and the directory where the files were supposed to be located was journal with a lower case j.
