如何编写expect脚本自动导入mysql数据库

Question

我的脚本是这样的
test.sh

#!/usr/bin/expect

set password  root
spawn mysql -u root -p

expect "password:"
send "$password\r\n"
send "drop database blog_api;\r\n"
send "CREATE DATABASE `blog_api` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;\r\n"
send "exit;\r\n"
expect "Bye"
send "mysql -uroot blog_api < 2017-01-09-12:00:09.sql;\r\n"
expect "Enter password:"
send "$password\r\n"
interact

导出是没有问题的，但是导入的话没有效果，大神求教。。。

Answer 1

你脚本中已经设置了变量password的值，为什么不直接用shell呢，直接执行命令mysql -uroot -p $password blog_api < 2017-01-09-12:00:09.sql或者写成shell脚本不就可以导入了。

Answer 2

为啥非要用expect呢，这个命令命名可以直接用shell来写的

#!/usr/bin/env bash
mysql -uroot -p 'root' -e 'drop database if exists blog_api; CREATE DATABASE `blog_api` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;'
mysql -uroot -p 'root' blog_api < 2017-01-09-12:00:09.sql

如果非要用expect的话，试试下面这样

#!/usr/bin/expect

set password 'root'

spawn mysql -uroot -p -e "drop database if exists blog_api; create database `blog_api` DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;"
expect "password:"
send "$password\r"
expect eof

spawn mysql -uroot blog_api < 2017-01-09-12:00:09.sql;
expect "password:"
send "$password\r"
expect eof
