== Link: Csh Programming Considered Harmful

Tom Christiansen's [[Csh Programming Considered Harmful
http://www.faqs.org/faqs/unix-faq/shell/csh-whynot/]] used to be posted
to various Usenet comp.unix groups, nigh on ten years ago or so. I
consider it sort of a pity that it isn't still being posted, because
every so often someone still decides that writing shell scripts in _csh_
would be a good idea.

Some of the problems Christiansen identified have since been fixed by
modern versions of _tcsh_, but not all of them.

(The article can also serve as an interesting catalog of _sh_
programming tricks.)
