not to start a thread or anything, but i used to use awk and sed for all
my text processing needs, before i ever knew what perl or linux was.
i'd call awk alot of things: powerful, stable, old.   i'd never call it
"pleasant".  for one, its error messages are very close to useless[1].

i'm not sure i'd call it easy to learn[2], either.  i've written some
pretty hairy awk scripts.

i'd certainly call it older than perl.

[1]: i used awk/sed exclusively on a sunos machine, before i ever knew
about linux.  i've never used gawk.  maybe gawk is easier to use and has
better error reporting.  but sun's awk on sunos was ridiculous.  the
time differential between using awk/sed and using perl for advanced text
processing is absurd.

[2]: a common joke is to say that the complexity of a topic is
proportional to the number of pages of an o'reilly book.  you can't take
this too seriously (advanced perl is a very thin book), but fwiw,
awk/sed is larger than the perl/tk and apache books.
