I love AWK; it (and perl) have saved my bacon many times. If your problem
involves processing fields within lines of an I/O stream in a *nix environment,
of course you or I should use AWK. Particularly me, since I'd never be given a
processing task involving more math than a "gozinta" or takeaway, much less
anything involving polynomials, natural logs, verb inverses, factorials, ranks
above 3, and a whole bunch of stuff that J would do for me if only I understood
what it was.
(I would also pick AWK if I had only 5 minutes to learn a new language.)
But had AWK never been invented (shudder), and I needed to write it, would I
use J? Well, not me, but I know some folks here that might knock it out using J
in an afternoon or two.
