Hi Jaben,
Please help review the attached patch.
In Shell, if we run a command containing the '|' in a double-quoted string, 
Shell will treat '|' as a split instead of knowing it's in quotes and skipping 
it. For example command  echo "a+b | ls" will have the output:   'ls"' is not 
recognized as an internal or external command, operable program, or script 
file. The patch add the code to check whether the '|' is in quotes.
