clobbering with >&

clobbering with >&

[Paul Ackersviller]

After using zsh for a while, I find myself gradually going back to the few
worthwhile features of csh, whch I used many years ago.

Here's something I don't see covered in the docs -- is it possible to
override the noclobber variable when doing output redirection with >&?
I've tried the obvious permutations of ! and | with it, but just get syntax
errors.

Never mind, I just answered my own question.  It appears >&\! will do the
trick.  Perhaps this should be documented.

Thanks to the workers for an amazing shell program.

What syntax errors?  Can you give a precise example, please?

Both >&| and >&! *should* work just fine, without the backslash.  Note that
you need a space after the `!' to prevent it being from taken as a history
reference, but even that isn't necessary with the `>&|' form.
