expect自动远程拷贝脚本,利用rsync命令,脚本内容如下:

#!/usr/bin/expect --

                        send "yes\r"

}

if { $yesnoflag == 2 } {
        expect {
                "assword:" {
                        send "$passwd\r"
                }
        }
}

expect {
        "assword:" {

                puts "OK_SCP: $ip\n"
                exit 0;
        }
}

用法:

./scp.exp

Usage: ./scp.exp ip user passwd port sourcefile destdir direction bwlimit timeout

       sourcefile: a file or directory to be transferred
                   需要拷贝目录时目录名后不要带 /, 否则会拷贝该目录下的所有文件
       destdir:    the location that the sourcefile to be put into
       direction:  pull or push
                   pull: remote -> local
                   push: local -> remote
       bwlimit:    bandwidth limit, kbit/s, 0 means no limit
       timeout:    timeout of expect, s, -1 means no timeout
