如何让 Unity 启动器定期改变颜色

如何让 Unity 启动器随着时间的推移改变颜色？

答案1

简介

下面的脚本循环遍历颜色的十六进制值。它可以在登录时启动，也可以在需要时手动运行

获取脚本

可以直接从本文复制源代码，或者通过 github 按照以下步骤复制：

  1. sudo apt-get install git
  2. cd /opt ; sudo git clone https://github.com/SergKolo/sergrep.git
  3. sudo chmod -R +x sergrep

脚本文件将是/opt/sergrep/unity_launcher_rainbow.sh

要使脚本在每次登录时自动启动，请参阅如何在登录时自动启动应用程序？. 提供/opt/sergrep/unity_launcher_rainbow.sh（完整路径）作为命令

脚本源
