通过在shell脚本中用expect实现远程scp文件

通过在shell脚本中用expect实现远程scp文件：

 

 

使用expect前，需要先安装两个rpm包：

# rpm -ihv CentOS/expect-5.43.0-5.1.i386.rpm
# rpm -ihv CentOS/expect-devel-5.43.0-5.1.i386.rpm

#!/usr/bin/expect -f
set password 密码
spawn scp 用户名@目标机器ip:拷贝文件的路径 存放本地文件的路径
set timeout 300
expect "用户名@目标机器ip's password:" //注意：这里的“用户名@目标机器ip” 跟上面的一致
set timeout 300
send "$password\r"
set timeout 300 //此处设置超时时间，单位为秒，如果，拷贝文件比较大并且多时，应该将这个值调大一些。
send "exit\r"

expect eof

附：scp参数
-r：拷贝目录
-c：允许压缩

一个完整的例子

expect_scp.exp
========================================================================
 

#!/usr/bin/expect -f #Author by kevin #date is 2011-11-14 set password vcdog #download local host spawn scp -r root@192.168.1.107:/root/dba_tool/test /root/DBA_TOOL/ set timeout 3 expect { "yes/no" {send "yes\r";exp_continue} } expect [email protected]'s password: set timeout 3 send "$password\r" set timeout 300 send "exit\r" expect eof #upload remote host spawn scp -r /root/DBA_TOOL/t.txt root@192.168.1.107:/root/dba_tool/ set timeout 3 expect { "yes/no" {send "yes\r";exp_continue} } expect [email protected]'s password: set timeout 3 send "$password\r" set timeout 300 send "exit\r" expect eof

==========================================================================

测试验证：
# chmod +x ./expect_scp.exp
# expect ./expect_scp.exp

spawn scp -r [email protected]:/root/dba_tool/test /root/DBA_TOOL/
[email protected]'s password:
test 100% 12 0.0KB/s 00:00
spawn scp -r /root/DBA_TOOL/t.txt [email protected]:/root/dba_tool/
[email protected]'s password:
t.txt 100% 254 0.3KB/s 00:00
