Hi all.

I am currently trying to develop a java applicatio that will enable me
to shutdown or restart computers remotely. I am doing this by using
the command prompt code in order to perform the shutdown. For example
I am using shutdown -m \\computer name -r -f -t 30.

When I run this code in the command prompt and the computer cannot be
found on the network it comes up with a message saying that the
network path was not found. How can I read in the error message that
the command prompt provides from within my Java Application.

Does Windows cmd.exe support command pipes? If it does you can run one command
and pipe the output of that into another executable's standard input. The
second application just reads the data on its standard input.

Any help in this matter would be highly appreciated.

Try piping (if cmd.exe supports) command output to a java application and see
what it reads.
