In case anybody was wondering, I'm still alive. I've been inordinately busy lately and have been spending the majority of my free time online re-learning Ruby on Rails. I've also been digging into multi-master and circular replication schemes for MySQL and MySQL proxy. I plan on sharing some of the things I've learned sometime in the near future. Anyway, here's a handy tip that I just used this morning.
If you want to sort all the files in a directory by size, you can do the following:
ls -lsR | sort -nr
The sort command will order by the number of blocks in each file. The biggest files are at the top.
