echo * | xargs rm
That's what I've been using in such cases for 15 years.
Works in every shell. (Do not use it in world-writable
directories, though; it can be exploited. But the same
is true for "rm *", too.)
You can, of course, put Simon's xrm() shell function in
your shell startup script (I was about to suggest a
similar function, but Simon beat me to it). You can
even call it rm so you can type "rm *" and it'll handle
any size of arguments.
The only problem is that you need to remember it when
you're logged into a machine where you don't have that
function. And when writing (portable) shell scripts,
Another problem is that that function solves the problem
for rm only. You would need similar functions for grep,
sed, cat, tail and so on. The xargs solution is generic
because it can be combined with every tool, so it's more
in the spirit of UNIX.
