问题描述
比方说,我试图写有三个提示一个test.sh的期望脚本:PROMPT1,PROMPT2,prompt3
Let's say I am trying to write an expect script for a test.sh that has three prompts: prompt1, prompt2, prompt3.
我的code是这样的:
My code is like this:
spawn test.sh
expect "prompt1"
send "pass1"
expect "prompt2"
send "pass2"
expect "prompt3"
send "pass3"
不过,PROMPT2只出现一半的时间。如果PROMPT2不露面,预计脚本休息。我怎么会写期待code,它跳过PROMPT2如果它不显示?
However, prompt2 only occurs half the time. If prompt2 doesn't show up, the expect script breaks. How would I write expect code that skips over prompt2 if it doesn't show up?
编辑:
固定我的code:
/usr/bin/expect -c '
spawn ./test.sh
expect {
"prompt1" {
send "pass1\r"
exp_continue
}
"prompt2" {
send "pass2\r"
exp_continue
}
"prompt3" {
send "pass3\r"
exp_continue
}
}
interact return
此方式,脚本的其余部分执行并提供输出
This way, the rest of the script executes and provides output.
推荐答案
您可以期待许多内容:
expect {
"prompt2" {
send "pass2"
expect "prompt3"
send "pass3"
}
"prompt3" {
send "pass3"
}
}
