os.stdin上的golang io.TeeReader破坏了tty

Question

I am trying to create a program which connects to remote server over ssh and executes commands given by user.i use os.TeeReader on os.stdin to log all user inputs but this is breaking tty.

var bufferRead bytes.Buffer
sshstring:=user+"@"+host
cmd := exec.Command("ssh",sshstring,"-o StrictHostKeyChecking=no")
cmd.Stdout = os.Stdout
cmd.Stdin =io.TeeReader(os.Stdin,&bufferRead)
cmd.Stderr = os.Stderr
cmd.Run()
fmt.Printf("
History: %s", &bufferRead)

I am getting following warning on execution with broken tty

Pseudo-terminal will not be allocated because stdin is not a terminal

Answer 1

Use the -T ssh option. It must disable pseudo-terminal allocation.

# some code here
cmd := exec.Command("ssh",sshstring,"-o StrictHostKeyChecking=no", "-T")
# some code here

There are the -t option, which force pseudo-terminal allocation.

Check man ssh
