It was thus said that the Great Carlos Murillo once
stated:
If I remember correctly, dd was originally intended to emulate the dd
command on OS 360, so it doesn't look like any of the other Unix
commands. Originally, dd was used to deal with media produced by
other operating systems, which I think was the motivation for modeling
it after the dd command on OS 360. I recall reading this in the V6
manuals, so if anyone has easy access to a V6 they could check this.

What I was trying to say is that `ls' uses single letter options preceeded
by a dash (-l -a -F), `find' uses full words with a dash (-print -follow)
and `dd' uses words/abreviations without dashes (if=/dev/zero of=/dev/null
count=45) and all three are found on every Unix system (at least, all the
ones I've used and I've used a fair number of them).
-spc (And can you explain the insanely different
command line parameters
to ls (typical Unix command line), find and dd? All three, I think
are POSIX to some degree 8-)
Mhh, care to highlight a particularly nasty difference in ls? (dd I know).
When in doubt, use sed. Except for a certain bug in the HPUX 10.20
release, it behaves quite uniformly across the board.
