You could try testing the following things: $(cygpath d:/) # don't capture the output but execute cygpath in a subshell sh -c "cygpath d:/" # force the subshell to be "sh" $(cat /dev/null | cygpath d:/) # see if pipes work the same as input redirect $(cygpath d:/ > /tmp/cygpath.out) # see if redirecting output also affects it I'll let you know if I think of other things to try.
