如何通过Linux命令传递多个键盘输入

Question

I run a linux command that sometimes asks for user input (press y or n).

After that for the same command I need to pass (yes/no)

I always want to answer y,and after that yes, how can I pass this value automatically ?

For 1 argument I knew that we can use echo y|command

But,for multiple inputs I do not know how????

After Passing y, I should also able to give yes Is there a way???

Answer 1

Use yes Utility

You can use the yes command if you always want to pass the same value. For example:

yes | ./script.sh

Use Expect, Variables, or Configuration Files

If you need anything more complex, then yes usually can't do what you want directly. Instead, you should use expect to script complex interactions, or rewrite your shell scripts to use variables or configuration files to pass parameters.
