没有人提到它，但是Putty scp (pscp)有一个-pw选项作为密码。

文档可以在这里找到:https://the.earth.li/~sgtatham/putty/0.67/htmldoc/Chapter5.html#pscp

确保你有“期望”工具之前，如果没有，就这样做 # apt-get install expect 创建具有以下内容的脚本文件。(# vi /root/脚本文件) 生成SCP /path_from/file_name user_name_here@to_host_name:/path_to 预计“密码: 发送put_password_here \ n; 交互 使用“expect”工具执行脚本文件 # expect /root/scriptfile

您可以使用像expect这样的工具编写脚本(也有方便的绑定，比如Python的Pexpect)。

下面是一个如何使用expect工具的示例:

sub copyover {
    $scp = Expect->spawn("/usr/bin/scp ${srcpath}/$file $who:${destpath}/$file");
    $scp->expect(30,"ssword: ") || die "Never got password prompt from $dest:$!\n";
    print $scp 'password' . "\n";
    $scp->expect(30,"-re",'$\s') || die "Never got prompt from parent system:$!\n";
    $scp->soft_close();
    return;
}

Make sure password authentication is enabled on the target server. If it runs Ubuntu, then open /etc/ssh/sshd_config on the server, find lines PasswordAuthentication=no and comment all them out (put # at the start of the line), save the file and run sudo systemctl restart ssh to apply the configuration. If there is no such line then you're done. Add -o PreferredAuthentications="password" to your scp command, e.g.: scp -o PreferredAuthentications="password" /path/to/file user@server:/destination/directory

上面提到的所有解决方案都可以工作，只有当你安装了应用程序，或者你应该有管理权限安装除sshpass。

我发现这个非常有用的链接可以简单地在后台启动scp。

$ nohup scp file_to_copy user@server:/path/to/copy/the/file > nohup.out 2>&1
