Hal, I could not get the SHA1 Terminal command to work. When I tried, nothing happened. Clearly operator error, but (when you have too much spare time) please provide more detailed instructions.
If you got no error message immediately, then it was working. All you needed to do was wait. Did you panic and quit terminal prematurely perhaps? (it takes time for a 1 gig file... about 15-20 seconds on my speedy MBP). Or did the
$ prompt come back with no text at all... error or otherwise? (unlikely in this case, though many other commands do succeed silently).
If you still have one of those former downloads, you can try again (but it seems unnecessary now i suppose).
PS: in general, along with any "it didn't work" issues in terminal, also enclose a copy of the actual session text (including the command part entered by the user).
