def cmd(self):
    try:
        command = self.case.get("ssh_cmd")
        command = command.removeprefix(" ")
        PyLog().set_log("【执行cmd函数】:" + command)
        if command and command.startswith('scp'):
            ftp = self.ssh_client.client.open_sftp()
            _, server_file, local_file = tuple(command.split(";"))
            ftp.get(server_file, local_file)
            PyLog().set_log("【cmd执行结果】:" + "文件下载成功")
            print("文件下载成功")
        else:
            for command in command.split(';'):
                stdin, stdout, stderr = self.ssh_client.client.exec_command(command, timeout=5, get_pty=True)
                time.sleep(2)
                result = stdout.read(100)
                PyLog().set_log("【cmd执行结果】:" + result.decode('utf-8'))
                print(result)
    except Exception as e:
        # errr=stderr.read(100)
        PyLog().set_log("【cmd执行结果】:" + str(e))
        print(e)
        return

Running result and detailed error content

Run nc-nv -l -p 11190 -s 0.0.0.0; ^C when result returns no error
on top; ^C ; mresult returns not found command

Use ^C to simulate ctrl+c

The result I want to achieve, if you need a quick answer, please try "paid reward"

Pass in a string that simulates ctrl+C
