I'm pretty sure that for the specific case, you should use
setwd() and or getwd()
which work platform-independently.
For the general case, note that shell() is windows-only whereas
the similar (but different!) function system() is defined for
all platforms and it has a second argument 'intern' which when
set to TRUE returns the result "R internally", i.e. as a
character, so the answer to your first question might be
system("cd", intern=TRUE)
