bash 如何在linux bash中模拟按箭头键

how to simulate pressing an arrow key in linux bash

提问by mysticalstick

I've worked with powershell before but I'm new to linux bash scripts. Say I wanted to write a script that just presses a key (left arrow) in regular intervals (0.05s). How could I go about doing this?

我以前使用过 powershell，但我是 linux bash 脚本的新手。假设我想编写一个脚本，只需按固定时间间隔（0.05 秒）按下一个键（向左箭头）。我怎么能去做这件事？
