stacktrace in attachment.

Judging from the stacktrace, the problem is in GrepCommand's handling of its arguments when called with one argument. Not a problem with the shell's pipe implementation as such ...
#3
no. it is not a grep command bug, it's a bug of shell.
Without pipe grep gets an argument in ARG_EXPR. But when using grep after pipe in ARG_EXPR.getValue() == null.

I've checked in a fix. The problem was indeed in the way that the shell was executing commands in a pipeline. It was skipping the step of parsing the arguments, so no argument values were bound when the command's execute method was called.
