Hi,

What you need to remember is that all the cygwin programs
are compiled by a version of the gcc compiler that produces
**windows** programs. So cygwin installs a windows version
of 'ls', a windows version of 'grep', a windows version of
'rvxt', a windows version of 'bash', etc.

Also, remember that the DOS command prompt - command.com
(and the newer cmd.exe) both understand pipelines in the
same syntax as bash, so when you type the '|' character,
cmd.exe knows to connect the standard output of one
program to the standard input of the next.

These two factors explain why your command worked.

Regards,
/John Vincent.
