批量分发文件

检查是否安装expect
which expect
如果没有安装，
yum install expect -y

vi distribute_file.sh
#!/usr/bin/expect -f
#chmod 777 distribute_file.sh

password=
path=$1
topath=$2

while read -r ipline
do

expect<<-END
spawn scp $path root@${ipline}:${topath}
expect {
                "(yes/no)?" {send "yes\r"; exp_continue}
               "${ipline}'s password:" {send "${password}\r"}
               "Permission denied" { send_user "[exec echo "\nError: Password is wrong\n"]"; exit}
}
expect eof
exit
END
done < ipfile.txt

同目录下创建 ipfile.txt 内容为：
#批量添加目标主机ip

脚本使用方法：
sh distribute_file.sh 所传文件的绝对路径 文件传入目标主机绝对路径
