此腳本需要expect指令，使用前确認一下機器收否有安裝：which expect
思路：1.編寫好要追加到hosts檔案内容的檔案（IP_hosts_test）
2.編寫腳本檔案testRead.sh（嵌套expect，實作自動登入），讀取上面的檔案，擷取ip，然後登入到其他機器，追加hosts
#!/bin/bash
ips=`cat IP_hosts_test |awk '{print $1}'`
for ip in $ips
do
echo -e "\n-------------開始追加hosts檔案---------------------\n"
password='rootroot'
ip='127.0.0.1'
echo -e "\n\n$ip\n"
/usr/bin/expect<<EOF
spawn scp /tmp/IP_hosts_test [email protected]$ip:/tmp/
expect {
"(yes/no)?" {
send "yes\r"
expect "*assword" {
send "$password\r"
}
}
"*assword" {
send "$password\r"
}
}
spawn ssh $ip
expect {
"(yes/no)?" {
send "yes\r"
expect "*assword" {
send "$password\r"
}
}
"*assword" {
send "$password\r"
}
}
expect "*]#"
send "cat /tmp/IP_hosts_test >> /etc/hosts\r"
expect eof
EOF
echo -e "\n-------------追加hosts檔案結束---------------------\n"
done
