Belated addition: and, in fact, when I've written a script which I don't expect to need to do this type of iteration on again, I often enough will remove the 'cat' from the start of the pipeline and replace it with normal input syntax for whatever command came at the next stage of the pipeline, as a form of (probably premature) optimization. I just don't bother avoiding cat during development (including when I think the script may be revised again in the foreseeable future), or in interactive use. -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
