Quoting from the Net::Telnet pod:

Many command interpreters echo back the command sent. In most situations, this method removes the first line returned from the remote side (i.e. the echoed back command). See cmd_remove_mode() for more control over this feature.

It might help if you explained your problem in more detail. You might provide some code or at least try to characterize when cmd() returns the command you sent. You could also provide information like what shell is being used on the remote side and what command you see this behavior with.
