How to run multiple programs in a sequence?
提问by user1280282
I have three different executables to run in sequence, two of them are byte executables. I want to automatically run them in sequence. It requires user inputs also initially. How to automate this with a script? Can anyone redirect to some tutorial or examples?
我有三个不同的可执行文件要按顺序运行，其中两个是字节可执行文件。我想按顺序自动运行它们。它最初也需要用户输入。如何使用脚本自动执行此操作？任何人都可以重定向到一些教程或示例吗？

You can write a simple shell script for it.

You're requirements are pretty vague. "I need stuff to execute in sequence some which require user input". Bash affords us a lot of flexibility for addressing these issues on a case by case basis but to really give you a GOOD answer we would probably want to know what the commands are and what inputs are required. Just want to execute commands in sequence? semicolons are for you
你的要求很模糊。“我需要按顺序执行一些需要用户输入的东西”。Bash 为我们提供了很大的灵活性来逐案解决这些问题，但要真正给您一个好的答案，我们可能想知道命令是什么以及需要哪些输入。只想按顺序执行命令？分号是给你的
cmd1 ; cmd2; cmd3
Does it matter if one of the commands fails or should the second command only be executed upon successful completion of the first? If these exit codes matter you are probably better off using double &&
如果其中一个命令失败，或者第二个命令应该只在第一个命令成功完成后执行，这是否重要？如果这些退出代码很重要，那么最好使用 double &&
cmd1 && cmd2 && cmd3
A lot of times user inputs can be redirected into a program or specified within the command line using arguments for example:
很多时候，用户输入可以重定向到程序中或使用参数在命令行中指定，例如：
{ echo "remotecommand 1" } | telnet localhost 1234
or
或者
ssh -o StrictHostKeyChecking=no 192.168.1.1
Outside of that you are starting to require expect scripting. So you see there are many cases which can come up where automation is possible but without much to go on it's hard to give you a specific answer.
除此之外，您开始需要期望脚本。因此，您会看到很多情况下可以实现自动化，但没有太多事情要做，很难给您一个具体的答案。
