[Fwd: Re: grep bug]

   Hi Bob!

I am still curious about the weird behaviour of grep. look at this example:
$ echo foo | grep [A-Z]
foo
is explained through LC_COLLATE. but why does
$ echo foo | grep -o [A-Z]
not explain which character actually matched? For the other 
combinations, it does:
$ echo Foo | grep -o [A-Z]
F
$ echo Foo | grep -o  [AaBbCcDdEeFf]
F
$ echo foo | grep -o  [AaBbCcDdEeFf]
f

cheers,
Ronny

  Hi Bob!

Thank you very much for your reply. I didn't expect the collating 
sequence was changed to something strange like AaBbCc... for an en_* 
locale; with LC_COLLATE=C it works indeed as expected. Please excuse the 
inconveniences...

Cheers,
Ronny
