每天学一个 Linux 命令（60）：scp

scp [-12346BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file] 
    [-l limit] [-o ssh_option] [-P port] [-S program]
    [[user@]host1:]file1 ... [[user@]host2:]file2

-1  #指定使用ssh协议版本为1
-2  #指定使用ssh协议版本为2
-3  #指定两个主机之间的副本通过本地主机传输
-4  #指定使用ipv4
-6  #指定使用ipv6
-B  #使用批处理模式
-C  #使用压缩模式传输文件
-F  #使用指定的ssh配置文件
-i identity_file  #从指定文件中读取传输时使用的密钥文件
-l  #宽带限制
-o  #使用的ssh选项
-P  #远程主机的端口号
-p  #保留文件的最后修改时间，最后访问时间和权限模式
-q  #不输出复制进度信息
-r  #以递归方式复制
-S program  #指定加密传输时所使用的程序
-v  #显示传输过程的详细信息

#复制文件
scp root@192.168.1.2:/download/soft/nginx.tar.gz /download/soft/

#复制目录
scp -r root@192.168.1.2:/app/soft/mongodb /app/soft/

scp -l 80 mingongge@mingongge.com:/home/mingongge/backup.tar.gz
#也可以写成如下
scp -l 80 mingongge@mingongge.com:/home/mingongge/backup.tar.gz ./
