Linux 退出前等待

Question

#!/usr/bin/expect
# Test expect script to telnet.

spawn telnet 192.168.1.1
expect "Username: "
send "adminpldt\r"
expect "Password: "
send "password\r"
expect "$"
send "show lan\r"
send "show\r"
expect eof
close
# end of expect script.

问题是，当我运行这段代码时，它显示了正确的输出。但之后并不会退出，就像等待输入一样。就像超时一样。但如果我删除该行 “期望 EOF”。它立即终止。有人能帮我吗？我刚刚开始学习 Linux 脚本，并且在 stackoverflow 上搜索了每个主题

我明白了。 eof 是当它返回到 bash 时。当我完全掌握了路由器配置后，我才意识到这一点。
