Python scp文件到用户输入远程计算机

Question

我正在尝试编写一个脚本，该脚本会将来自用户输入的文件scp传输到远程计算机。 我只能使用os.system，因为我不允许安装paramiko。

这是我的代码

 #! /usr/bin/python import os import subprocess ##Define source + destination source = raw_input("Source: " ) destination = raw_input("Destination: ") username = raw_input("SSH Username: ") def result(): d = dict(); d['src'] = source d['des'] = destination d['usr'] = username return d d = result() print(d) ##Locate Backup File def backup_file(): os.system('ls *DBAPP*') return x = backup_file() ##SCP Backup file to remote host bdir = ":/home" remote_host = username + "@"+ destination + bdir question = raw_input("Do you wish to continue? y/n ") if question == "y": print("Copying file to " + str(remote_host)) os.system('sudo scp ' + str(x) + str(remote_host)) else: raise SystemExit 

我不确定将x作为字符串放入os.system是否会正常工作。 我收到此错误消息：

 [user@server ~]$ ./lftp_install.py Source: xxxxx Destination: xxxxxx SSH Username: xxxxxx {'src': 'xxxxx', 'des': 'xxxxx', 'usr': 'xxxxx'} DBAPP Do you wish to continue? y/ny Copying file to user@remoteserver:/home usage: scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] [-l limit] [-o ssh_option] [-P port] [-S program] [[user@]host1:]file1 ... [[user@]host2:]file2 [user@server ~]$ 

请帮忙谢谢！
