That's why it is "a nice tradition" to indicate which
kind of shell a command should be issued to, for example

	% set x = 100; foreach y ( .... ) >& boo_$x

which is for C shell (tcsh), versus

	$ Q=1; W=2; [ ${Q} .... ] && meow `ls` < hi.there

which is for (ba)sh. It get's interesting when talking
about commands to be issued as root. :-)

	# pwd

The article basically concentrates on shell PROGRAMMING,
and I agree that programming scripts is not the biggest
stength of the C shell. On the other hand, it's a very
good interactive command line interpreter (as mentioned
before) that is, in some regards (mainly driven by very
individual taste), superior to the hyped bash. But it's
also worth mentioning that there are even better shells
which combine "the best of both worlds", like zsh, a shell
that many professionals seem to prefer over the other
ones mentioned.
