The '*' is unnecessary anyway.
It's totally necessary. root@hobbit:/var# du -sh 2.1G . root@hobbit:/var# du -sh * 4.0M backups 124M cache 40K games 209M lib 4.0K local 0 lock 1.8G log 8.0K mail 4.0K opt 2.3M qmail 0 run 3.6M spool 32K tmp In my case, most of the space is in the "log" subdirectory. So, if I felt a need to prune stuff on this system, I would cd into log next, and repeat the process, until I found something I felt it was safe to truncate or remove. (Removing log files is often ineffective, because they're kept open by whatever's writing to them; truncating them works, though.)
