因为使用时间的增长， Ubuntu系统中的文件会逐渐增多，导致磁盘空间不足。本文将为您介绍多种方法，帮助您巧妙清理Ubuntu文件管理磁盘空间，释放宝贵的存储空间。

清理回收站

回收站是Ubuntu系统中存放被删除文件的临时存储位置。定期清理回收站可以释放一定量的磁盘空间。

操作步骤：

• 打开文件管理器。
• 在左侧导航栏中找到“回收站”文件夹。
• 选择要删除的文件，然后右键单击并选择“删除”。
• 清空回收站：选择“回收站”文件夹，然后点击上方工具栏的“清空回收站”按钮。

清理apt缓存

apt缓存是存储已下载软件包的目录，长时间积累会占用大量磁盘空间。

sudo apt clean

清理未使用的deb包

删除未使用的deb包可以释放大量磁盘空间。

sudo apt-get autoclean

清理临时文件

系统会生成一些临时文件，占用磁盘空间。

sudo rm -rf /tmp/*

清理系统日志

系统日志文件会随时间增长占用大量空间。

journalctl --disk-usage

使用Baobab分析工具

Baobab是一个图形化的磁盘空间分析工具，可以帮助您直观地查看磁盘使用情况。

• 打开软件管理器。
• 搜索“Baobab”。
• 安装Baobab。
• 启动Baobab，选择要分析的磁盘。
• 后来啊，删除不必要的文件和目录。

清理大容量软件包

删除不必要的软件包可以释放大量磁盘空间。

• 打开软件管理器。
• 搜索并卸载不必要的软件包。

清理旧内核

旧内核版本会占用磁盘空间，且不会自动删除。

• 打开终端。
• 施行以下命令：

  sudo apt-get remove $(dpkg-query -W -f='${binary:Package}==${Version}' $(grep '^ii' /var/lib/dpkg/status | grep 'linux-image' | cut -d' ' -f3 | sort -u | grep -v '^linux-image-' | grep -v
