#! /Bin/sh

_ Tty_setting = $ (stty-g)

Stty-icanon

Stty-echo

# We can use c2 arguement to use keyboard shortcut cut with 2 characters.

_ Key_press = $ (head-c1)

Stty $ _ tty_setting

# The following section describes how to judge the input.

Case $ _ key_press in

A) echo-en "here we can replace it with the command string we want to execute 1 \ n"

;;

2) echo-en "here we can replace it with the command string we want to execute 2 \ n"

;;

3) echo-en "here we can replace it with the command string we want to execute 3 \ n"

;;

4) echo-en "here we can replace it with the command string we want to execute 4 \ n"

;;

5) echo-en "here we can replace it with the command string we want to execute 5 \ n"

;;

6) echo-en "here we can replace it with the command string we want to execute 6 \ n"

Exit 1 ;;

*) Echo-en "here we can replace it with the script help information-related command \ n"

Stty is used to display and modify terminal settings. This complex command can be used in scripts to control terminal behavior or display output methods. Combined with special characters and case or other conditions, we can easily search files by pressing Ctrol + F.

Script. Stty-g is used to record stty parameters. After the terminal is modified, it is restored in time after use.

Stty-echo is commonly used to require users to enter passwords.
