推荐答案

您应该找到'期待'命令将做你需要它做什么。它的广泛使用。看到这里的一个例子：<一href=\"http://www.thegeekstuff.com/2010/10/expect-examples/\">http://www.thegeekstuff.com/2010/10/expect-examples/

You should find the 'expect' command will do what you need it to do. Its widely available. See here for an example : http://www.thegeekstuff.com/2010/10/expect-examples/

（非常粗略的例子）

#!/usr/bin/expect
set pass "mysecret"

spawn /usr/bin/passwd

expect "password: "
send "$pass"
expect "password: "
send "$pass"
