求助 expect: 如何使用expect执行自定义的脚本

ouyangting_2000

尝试在java启动的语句前加上了nohup，发现进程被神奇的启动了，但是expect脚本却报了一个超时的错误。

想问一下waker大大，我的shell启动脚本在最后一句应该结束了，为什么会有timeout这样的错误？

expect: does "" (spawn_id exp4) match glob pattern "EOF"? no
看输出日志，应该是在等EOF，一直没等到才报的timeout，我感觉不影响结果，请高手定夺

结果的确不影响，应用也启动起来了，但是timeout的结果总让我想不通。

请对比一下
eof
EOF

谢谢提点，我改成了小写的eof，但是仍然报超时，我能不能理解为我执行的shell脚本并没有文件结束符，所以expect脚本一直等待到超时？

我试了一下，在expect eof之前，先退出spawn启动的脚本，就能正确read eof了。
所以，在expect eof之前，可以加以下两句：
expect "*"
send "exit\r"
这样就不会出现timed out了
