Host command with rsh?

ruby-talk
1

Hi,

I am trying to launch a host command to windows, the command is something like
"rsh myaixmachine -l myuser “export PATH=/pvcsbindir:$PATH; vlog mypvcsarchive > tomyfile; echo”"

I would like to get the standard output for this command. But it does not work properly : I need to do in my Windows console window, and if I launch several such commands, it happens I am really stuck.

It works with simple commands to Windows. And it works also when I try some prepared command with mycommand

An idea to this problem ?

Regards,
Jérôme Hauss

PS. One of my simple tries

def rsh(myaixmachine, command)
@t = nil
s = "rsh " + myaixmachine + " -l myuser “#{ command }”"
puts s
@pipe = IO.popen(s)
@t = @pipe.read
@pipe.close
@t
end

You can use net/telnet instead

require ‘net/telnet’

c=%^export PATH=/pvcsbindir:$PATH; vlogmypvcsarchive > tomyfile; echo "^

s = Net::Telnet.new({“Host” => “myaixmachine”)

s.login(“myuser”,“password”)

p s.command(c)

s.close

Thank you Rodrigo,

I have discovered that my example with IO.popen works fine if I use the -n
option of Windows’ rsh.
(this option redirects the input of RSH on NULL)
