     ^ is the quoting character for NT's CMD.EXE (bash doesn't exhibit 
this problem).  Also note that CMD.EXE requires | must be double 
quoted if you're passing it through a pipe (again bash doesn't need 
this):

F:\temp>echo ^| | cat
The syntax of the command is incorrect.

F:\temp>echo ^^^| | cat
|

F:\temp>bash
$ echo \| | cat
|
$ echo \\\| | cat
\|

Follow start menu => help => Windows NT commands => command symbols 
for docs on CMD.EXE's special characters.  Or just spend you time in 
bash, which is friendlier and more featureful:-)
