This is the downloaded .AppImage file. We need to give it executable rights. Before that, we can change the owner of the file to ourselves instead of root, so that no root permission is required for future operations on the file.

mv [当前文件路径] [目的文件路径]  // 转移文件到我们想要存放的地方
sudo chown [用户名] [文件或目录名] // 修改文件所有者
chomd +x marktext-x86_64.AppImage // 可执行权限

3. Desktop icons

In order to make it easier for us to double-click on the desktop to open the software like using windows, we need to write a **.desktop** file on the desktop

touch marktext.desktop
vim marktext.desktop

The content of the file is as follows:

[Desktop Entry]
Name=MarkText
Comment=Next generation markdown editor
Exec=/opt/soft/markdown/marktext-x86_64.AppImage %F
Terminal=false
Type=Application
Icon=/opt/soft/markdown/marktext.png
Categories=Office;TextEditor;Utility
MimeType=text/markdown;
Keywords=marktext;
StartupWMClass=marktext
Actions=NewWindows
StartupNotify=true

[Desktop Action NewWindows]
Name=New Window
Exec=/opt/soft/markdown/marktext-x86_64.AppImage %F
Icon=/opt/soft/markdown/marktext.png

There are several parameters in this file that need to be modified by yourself, and the rest can be copied directly

Exec=AppImage文件所在的绝对路径，后面的%F务必加上，为关联文件，跟后面的右键添加打开方式有关
Icon=软件logo所在的绝对路径，软件的logo图片下面给出
其他属性的说明可以参考文末最后一个参考连接
