以pycharm举例
1 首先安装软件，例如安装到 /usr/local/src/pycharm-2018.2.7
2 在 /home/用户名/.local/share/applications 文件夹下新建 jetbrains-pycharm.desktop
3 jetbrains-pycharm.desktop 内容如下
[Desktop Entry]
Version=1.0

Exec="/usr/local/src/pycharm-2018.2.7/bin/pycharm.sh" %f

添加后，在开始菜单，也就是 application finder 中就能找到对应软件的快速启动按钮啦
