Linux scp命令
Linux scp命令用于Linux之间复制文件和目录。
scp是 secure copy的缩写, scp是linux系统下基于ssh登陆进行安全的远程文件拷贝命令。
语法
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简易写法:
scp [可选参数] file_source file_target 参数说明：
-1： 强制scp命令使用协议ssh1
-2： 强制scp命令使用协议ssh2
-4： 强制scp命令只使用IPv4寻址
-6： 强制scp命令只使用IPv6寻址
-B： 使用批处理模式（传输过程中不询问传输口令或短语）
-C： 允许压缩。（将-C标志传递给ssh，从而打开压缩功能）
-p：保留原文件的修改时间，访问时间和访问权限。
-q： 不显示传输进度条。
-r： 递归复制整个目录。
-v：详细方式显示输出。scp和ssh(1)会显示出整个过程的调试信息。这些信息用于调试连接，验证和配置问题。
-c cipher： 以cipher将数据传输进行加密，这个选项将直接传递给ssh。
-F ssh_config： 指定一个替代的ssh配置文件，此参数直接传递给ssh。
-i identity_file： 从指定文件中读取传输时使用的密钥文件，此参数直接传递给ssh。
-l limit： 限定用户所能使用的带宽，以Kbit/s为单位。
-o ssh_option： 如果习惯于使用ssh_config(5)中的参数传递方式，
-P port：注意是大写的P, port是指定数据传输用到的端口号
-S program： 指定加密传输时所使用的程序。此程序必须能够理解ssh(1)的选项。
实例
1、从本地复制到远程
命令格式：
scp local_file remote_username@remote_ip:remote_folder
# 或者
scp local_file remote_username@remote_ip:remote_file
# 或者
scp local_file remote_ip:remote_folder
# 或者
scp local_file remote_ip:remote_file 第1,2个指定了用户名，命令执行后需要再输入密码，第1个仅指定了远程的目录，文件名字不变，第2个指定了文件名；
第3,4个没有指定用户名，命令执行后需要输入用户名和密码，第3个仅指定了远程的目录，文件名字不变，第4个指定了文件名；
应用实例：
scp /home/space/music/1.mp3 [email protected]:/home/root/others/music
scp /home/space/music/1.mp3 [email protected]:/home/root/others/music/001.mp3
scp /home/space/music/1.mp3 www.runoob.com:/home/root/others/music
scp /home/space/music/1.mp3 www.runoob.com:/home/root/others/music/001.mp3 复制目录命令格式：
scp -r local_folder remote_username@remote_ip:remote_folder
# 或者
scp -r local_folder remote_ip:remote_folder 第1个指定了用户名，命令执行后需要再输入密码；
第2个没有指定用户名，命令执行后需要输入用户名和密码；
应用实例：
scp -r /home/space/music/ [email protected]:/home/root/others/
scp -r /home/space/music/ www.runoob.com:/home/root/others/ 上面命令将本地 music 目录复制到远程 others 目录下。
2、从远程复制到本地
从远程复制到本地，只要将从本地复制到远程的命令的后2个参数调换顺序即可，如下实例
应用实例：
scp [email protected]:/home/root/others/music /home/space/music/1.mp3
scp -r www.runoob.com:/home/root/others/ /home/space/music/说明
1.如果远程服务器防火墙有为scp命令设置了指定的端口，我们需要使用 -P 参数来设置命令的端口号，命令格式如下：
#scp 命令使用端口号 4588
scp -P 4588 [email protected]:/usr/local/sin.sh /home/administrator2.使用scp命令要确保使用的用户具有可读取远程服务器相应文件的权限，否则scp命令是无法起作用的。
