Well, I'm, not sure why, but this results in the output from "od" being on
stderr; when reading TFM about the "1<&2" construct it sheds no light on
reality.

Anyway, the following is sufficient to dup stderr from the subshell to its
stdout for the Bourne shell:

(cat no_file1; cat no_file2) 2>&1 | od -xc
