command-line build: output to stdout instead of log ?

fooling around w/ building our stuff from the osx command-line. i would love to get Unity's build output (and my own buildscript logging) into stdout instead of the unity log. it's much easier to grep it, capture it, etc that way.

the only thing i've come up with is something like this in bash: <unity app> <options> & sleep .25 && tail -f <unity log> but it's pretty inelegant and it moves the unity build into a background thread where it can be unclear if it's still living or dead, etc.
