Claudio,

No, that's not a bug. It's just a (system-dependent) limit shared by all 
POSIX-compliant systems. The actual limit happens to be on the low side 
under Cygwin.

Familiarize yourself with the "xargs" command. It's there just to handle 
these cases.

Also, in many cases the programs themselves process directories and don't 
need to have each file within the directory passed to them as an argument. 
Ls certainly does this (hence your "ls *" example has an equivalent without 
limits: plain old "ls") and the grep family has a -R (recursive) option 
that's related.

The reason you don't see the problem from a DOS command prompt is that 
argument handling (in particular, wild-card processing) is different when 
Cygwin programs are invoked from a DOS CMD.exe or Command.exe shell and 
that difference effectively side-steps the limit you experience when 
running under a Cygwin shell (BASH, zsh, tcsh, ash, etc.).

Good luck.
