为 ubuntu 下 .AppImage 运行文件快速生成桌面和任务栏图标 .sh 文件

I had a friend make an install sh file: It seems to work well and I get an icon added to my ubuntu left app shortcut bar. Here it is below. I will deliver a zip with the app logo and sh file.
It could be modified to help others. I don’t want to recommend or use for myself the appImage installer app. I’m more comfortable with a bash script for myself and logically what I would give others too. This does not require any root privs ans will be accepted better just like appImages over deb.
Nevertheless, this is dependent on the desktop file rather than the appImage produced in contrast to kdenLive appImage that works fine.

#!/bin/bash

appimages=${basename}.AppImage

desktopfile=${basename}.desktop
