comment Alternative to xxd that returns bytes?
Also tried echo "foo" | openssl sha1 | hexdump -v -e '8/1 "%02X"', but this gives the wrong answer, or at least an answer that differs from xxd on Linux.

comment Alternative to xxd that returns bytes?
On Linux, echo "foo" | openssl sha1 | hexdump '8/1 "%02X"' - gives error messages: hexdump: 8/1 "%02X": No such file or directory, hexdump: -: No such file or directory, and hexdump: -: Bad file descriptor. If I leave out the stdin descriptor, then I get hexdump: 8/1 "%02X": No such file or directory and hexdump: 8/1 "%02X": Bad file descriptor errors. I haven't tried this on Mac OS X, yet, but it does come with hexdump. Any thoughts?

comment Alternative to xxd that returns bytes?
It works for me on Linux, but not for Mac OS X 10.8.2 on my MacBook Air. Neither the pre-installed version of xxd nor the one I compiled. xxd -p works, but xxd -p -r gives a blank string. Is there an alternative to xxd that works the same as xxd -p -r?

What options do I use with hexdump to get byte output? I can get hex output, but I don't see what option to use to get byte output identical to what xxd outputs.

Yep, that's the problem with this command, as far as making output from only a few frames.

Here's a link to the movie output: dl.dropbox.com/u/31495717/jigsaw.mp4 (this is the same as foo.mp4)

No break. Same result using the glob. Did not try cat. I'll try to upload the movie file to Dropbox a little later when I have my laptop again.
