want shell should I learn 6

There's nothing to learn - just as there is nothing to learn in bash for use as an interactive shell: one types the command to execute the command: one hits the cursor keys to scroll through the command history. Etc. The advantage is that tcsh is friendlier because it does not expect of you the exactness of a programming language - it corrects spelling errors for one. It's more forgiving and helpful by a long way. Even the command completion is nicer (I have never been able to work out bash's ctl-p or whatever it is - it's incomprehensible in the same way that all presumably emacsy things are incomprehensible to me).

And "inferior" syntax (in your terms) is better for a human. Thanks.

Of course you can (given a tcsh script to cut and paste). Maybe I missed something in your example - I deleted it before looking. Maybe it had some subtle thing with stty in .

Eh? Of course you can (buttuming that you mean tcsh functions). But why on earth would you want to? Please stop with the fixation on PROGRAMMING. It's of absolutely no interest in an interactive shell - a nastiness that one doesn't want. I butture you I proram just fine in java and sh and ML and C and C++ and gofer and prolog and and and ... but I do not want them sticking themselves in on my command line.
