Pretty good. However, POSIX 1003.2 compliant shells (e.g., bash) allow
the use of $(date) as well as `date`. This has the advantage that it
can be nested:
head -1 $(foo $(bar))
This will run the "foo" command with 1 argument -- the result of the
"bar" command -- and return the top line of the resulting output.
