如何在没有匹配时使用expect发送命令

Question

当期望值不匹配时，是否可以发送默认命令？

我想让参赛者参赛，直到比赛结束？

set timeout 60
expect {
timeout {
puts "Failed to find foo"
exit 1
}
"foo" {
exit
}
default {
send "r"
}
}

Answer 1

您可以期望行尾发送回车：expect将行尾转换为rn

expect {
timeout {
puts "Failed to find foo"
exit 1
}
"foo" {
exit
}
"rn" {
send "r"
exp_continue
}
}
