这确实是 paramiko SSH exec_command(shell script) 在完成之前返回，但是那里的答案不是很详细.所以...

This is indeed a duplicate of paramiko SSH exec_command(shell script) returns before completion, but the answer there is not terribly detailed. So...

如您所见，exec_command 是一个非阻塞调用.因此，您必须使用以下任一方法等待远程命令完成:

As you noticed, exec_command is a non-blocking call. So you have to wait for completion of the remote command by using either:

• Channel.exit_status_ready 如果你想对命令完成进行非阻塞检查(即:池化)
• Channel.recv_exit_status 如果你想阻塞直到命令完成(并返回退出状态——退出状态为 0 表示正常完成).

在您的特定情况下，您需要后者:

In your particular case, you need the later:

stdin, stdout, stderr = client.exec_command(filedelete)  # Non-blocking call
exit_status = stdout.channel.recv_exit_status()          # Blocking call
if exit_status == 0:
    print ("File Deleted")
else:
    print("Error", exit_status)
client.close()
