Bash 调用将输入传递给命令的Shell脚本，该命令需要来自终端的输入

我正在尝试编写一个脚本来调用以下命令

[root@xxxxx imtadmin]# admin tower

-------------------------------------------------------------------
GMS: address=xxxxx-42450, cluster=CLRTY-SA, physical address=xxxxx:45155
-------------------------------------------------------------------

我的脚本确实调用命令admin tower并在提示符>处停止，但它不接受脚本提供的输入或我从终端提供的输入（我的目标是从脚本提供输入）。

这应该可以：

send "list clients\n"
expect eof

---

下面的步骤奏效了。谢谢，@Philippe暗示我需要在提供输入后添加expect

#!/usr/bin/expect

spawn /opt/clarity/bin/admin tower
expect -re "^>"
send "list clients\r"
expect -re "^>{1}"
send "refresh\r"
expect -re "^>{1}"
send "list clients\r"
expect -re "^>{1}"
send "exit\r"

---

据我所知，Philippe所做的不仅仅是暗示。在发送“exit”之后，您应该

期望eof

以允许管理程序优雅地退出。在运行每个命令之后，我返回提示符>我应该使用expect eof还是expect-re“^>{1}”？

期望eof

用于识别生成的进程何时结束。如果您发送一个命令并期望得到一个提示，那么

expect-re{>$}

（这是另一个识别提示的正则表达式：一个尖括号和一个行尾空格）。我假设您不希望在发送“退出”后出现提示。没错，我不希望在退出后出现提示。它将退出管理程序。不确定是否必须使用。如果您喜欢编写shell脚本，可以查看我的。

#!/usr/bin/expect

spawn /opt/clarity/bin/admin tower
expect -re "^>"
send "list clients\r"
expect -re "^>{1}"
send "refresh\r"
expect -re "^>{1}"
send "list clients\r"
expect -re "^>{1}"
send "exit\r"
