I have a lot of friends who started out learning about unix concepts using linux. And many of them are now migrating over to freeBSD. They are used to the "free" command to look up ram/memory usage. I found a perl script written for freebsd that sort of mimics this command. I normally just use "top", "sysctl" or "vmstat" command myself. However, this is a pretty cool little perl script and might be handy in someones BSD toolbox out there. Here is the link.

Have fun!
Here is what the output looks like on my computer running freeBSD-7.1 prelease using this perl script.
