If you use unix, you should probably do this:

rsh machineA command

This will return the standard output, just as if you ran it on the local machine.

If you want also to save the output to a file then do

rsh machineA 'command | tee filename'

(it is usually safer to use ssh instead of rsh, although this requires more proccessing on each side for the encryption/decryption)


Cheers.
