yes, but what i was referring to was the command line options. everyone has
`stat`, but it's really only the GNU stat that supports the '-c fmt' option
using the semantics necessary here. `wc -c` is going to work everywhere, but
i would need to figure out what OS i'm on and where `stat` is coming from so i
would know how to properly invoke it.
