Filename Generation - *(.)

Filename Generation - *(.)

[Atom Smasher]

these do what i'd expect:
  ls ./*(.)    # list all regular files in the current dir
  ls *(.)      # list all regular files in the current dir
  grep foo ./*(.)    # grep 'foo' from regular files in the current dir

this doesn't:
  grep foo *(.)

can anyone explain that?

zsh 4.3.4 (amd64-portbld-freebsd6.2)

In which way does it not work?

Would you have a file whose name starts with "-" in the current
directory and a GNU grep by any chance?

In any case, when passing /unknown/ arguments (practically, if
you can't make sure none of them may start with a - or +), you
need to mark the end of options:

grep foo -- *(.)

Oops,

sorry, end of options goes after the options and before the
remaining arguments obviously.

grep -- foo *(.)

standard greps don't recognise options after the first
non-option argument, so

grep foo *(.)

would be OK. But GNU grep (unless called in POSIX mode, as GNU
utilities in general) has the problem.
