1.paramiko模块
<pre><code>执行screen之类的命令应使用invoke_shell()
client=paramiko.SSHClient()
key=paramiko.AutoAddPolicy()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(ip, port, username=username, password=password,timeout=30)
chan = client.invoke_shell()
chan.send(&#039;screen -S a -d -m btfs/bin/btfs daemon\n&#039;)

记得加\n与sleep(1)
2.apt安装直接确认不输入y/yes

3.cmd中执行powershell指令（只允许将表达式作为通道第一个元素）

4.powershell处理文件第n行范围
<pre><code>if ($_.ReadCount -ge 167 -and $_.ReadCount -le 170) 
{
 $_ -replace &#039;false&#039;,&#039;true&#039;
} 
else 
{
 $_ 
} </code></pre>

 		proxy_set_header X-Real-IP $remote_addr;
 		proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 		proxy_connect_timeout 600;
