That depends on where you think you're data is going to get corrupted.
If you think something might throw a space in the middle of one of
the the other colums (e.g. "s g F01010"), (split)[-1] will work
better. On the other hand, if you think your input may contain
something like this at you:
6 2005/02/28 22:47 180 100% -il-o-b----- sg F01005 !error:
you need to grab (split)[7]. For general use, I thinkit's basically
a matter of personal preference.
In this case, it probably doesn't really matter: He's done 2>&1 on
the piped open, so there's no way to predict when the buffers will be
flushed or where stderr will be inserted into stdin. some of the
input is going to be munged either way.
