I wrote my own utility which works a bit differently. Instead of calling cd, I call a different function which changes to a directory stored by an alias in a DBM database. Any time I'm in a directory that I know I'll want to revisit frequently, I call another function to save the current directory (by alias) to the database. Another shell function lists the current aliases in the database and what directories they point to. It's a bit of a hack (a combo of Perl and bash scripting) -- something anyone on HN could probably put together in no time, but it does the job. I've been using it for 2 or 3 years now, and I find it to be extremely useful and a decent time saver.
