I find that, for these kinds of utilities, all the extra add-ons tend to cost me more in the form of, "Whoops, we tried using this on $DIFFERENT_UNIX and it broke," than they ever save me. When I'm looking to do something more complicated, I'd rather look to tools from outside the POSIX standard. The good ones give me less fuss, because they can typically be installed on any POSIX-compliant OS, which is NBD, whereas extensions to POSIX tools tend to create actual portability hassles.
