如果你观察到一个严格的主机密钥检查错误，那么使用-o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null选项。

完整示例如下 sshpass -p "password" scp -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null root@domain-name.com:/tmp/from/psoutput /tmp/to/psoutput

下面是基于这篇博文的一个穷人的Linux/Python/ expect样例:将简单的shell升级为完全交互式 tty。对于无法安装Expect或向Python添加模块的旧机器，我需要这个功能。

代码:

(
    echo 'scp jmudd@mysite.com:./install.sh .'
    sleep 5
    echo 'scp-passwd'
    sleep 5
    echo 'exit'
) |

python -c 'import pty; pty.spawn("/usr/bin/bash")'

输出:

scp jmudd@mysite.com:install.sh .
bash-4.2$ scp jmudd@mysite.com:install.sh .
Password: 
install.sh                                 100%   15KB 236.2KB/s   00:00    
bash-4.2$ exit
exit

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

您可以使用以下步骤。这对我很管用!

步骤1 - 创建一个普通的文件，假设“fileWithScpPassword”，其中包含目标服务器的ssh密码。

Step2-使用sshpaas -f后跟密码文件名，然后是正常的scp命令。

sshpass -f“scppassword”scp / filepathtou上传user@ip:/目的地目的地/

使用sshpass:

sshpass -p "password" scp -r user@example.com:/some/remote/path /some/local/path

所以密码不会显示在bash历史记录中

sshpass -f "/path/to/passwordfile" scp -r user@example.com:/some/remote/path /some/local/path

上面的操作将路径的内容从远程主机复制到本地。

安装:

ubuntu / debian 安装sshpass centos / fedora Yum安装sshpass MAC / macports 端口安装sshpass MAC / brew brew install https://raw.githubusercontent.com/kadwanev/bigboybrew/master/Library/Formula/sshpass.rb

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;
}
