unknown file attribute

unknown file attribute

[Manfred Lotz]

Hi there,
I accidentally found that:

$ echo (B)

yields:

zsh: unknown file attribute


Same for echo (C). However, echo (A) and echo (D) work. Any idea why
that happens?

I know I could type: "(B)". But I want to save typing the "s.

I knew there must be a setting to prevent it but didn't know how to
find it. 

no_bare_glob_qual does it nicely.

To Manfred:
If you don't want to learn glob qualifiers, "setopt no_bare_glob_qual".

These are glob qualifiers: qualifiers `B' and `C' do not exist (that is why you 
see this error), but qualifier `A' means `group-readable files' and `D' means 
`set GLOB_DOTS option for the current pattern'. As there is no pattern then no 
files match it and zsh will behave according to its options:
1. If nullglob is set unmatched pattern is removed from argumnents list and
   `echo (A)' yields just a single newline.
2. If cshnullglob and nomatch are unset unmatched pattern is left as-is and
   `echo (A)' yields `(A)\n'
3. If either cshnullglob or nomatch are set then unmatched pattern prevents 
command from executing and `echo (A)' will yield an error (either `zsh: no 
matches found: (A)' if cshnullglob is unset or `zsh: nomatch' if it is set).

I suggest you to learn this glob quilifiers as they are really useful in some 
situations.
