我的脚本：

#!/usr/bin/expect

spawn /opt/clarity/bin/admin tower
set timeout -1
expect -re "^>{1}"
send "list clients"

我的脚本确实调用了命令管理塔并在提示符处停止 > 但它不接受脚本提供的输入或我从终端提供的输入（我的目标是提供来自脚本的输入）。

Answer 1

这应该有效：

send "list clients\n"
expect eof

Answer 2

以下有效。谢谢，@Philippe 提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"
