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

  1. #!/usr/bin/expect -f
  2. #Author by kevin
  3. #date is 2011-11-14
  4. set password vcdog
  5. #download local host
  6. spawn scp -r root@192.168.1.107:/root/dba_tool/test /root/DBA_TOOL/
  7. set timeout 3
  8. expect {
  9. "yes/no" {send "yes\r";exp_continue}
  10. }
  11. expect root@192.168.1.107's password:
  12. set timeout 3
  13. send "$password\r"
  14. set timeout 300
  15. send "exit\r"
  16. expect eof
  17. #upload remote host
  18. spawn scp -r /root/DBA_TOOL/t.txt root@192.168.1.107:/root/dba_tool/
  19. set timeout 3
  20. expect {
  21. "yes/no" {send "yes\r";exp_continue}
  22. }
  23. expect root@192.168.1.107's password:
  24. set timeout 3
  25. send "$password\r"
  26. set timeout 300
  27. send "exit\r"
  28. expect eof

# chmod +x ./expect_scp.exp
# expect ./expect_scp.exp
spawn scp -r root@192.168.1.107:/root/dba_tool/test /root/DBA_TOOL/

spawn scp -r /root/DBA_TOOL/t.txt root@192.168.1.107:/root/dba_tool/
root@192.168.1.107's password:
