清洁脚本
此脚本将在控制台上执行最大的块：
- 清理apt缓存
- 删除卸载的.deb软件包中剩下的配置文件（如果您不将
--purge开关与一起使用，则会发生这种情况apt-get）
- 除去除您使用的内核以外的所有内核
- 清空每个用户（包括root）的垃圾
创建具有此内容的文件并赋予其可执行权限：

查找大文件夹和文件包
一些可以帮助您找到大文件夹和程序包的工具：
sudo apt-get install ncdu debian-goodies deborphan
sudo ncdu / # lists all folders by size on the console (like the gui `baobab`)
dpigs -H # shows large packages that you don't use
man deborphan # finds packages that have no packages depending on them
deborphan --guess-all --libdevel | xargs apt-get -s purge
局部冲动
使用localepurge卸载系统中未使用的语言：
sudo apt-get install localepurge
删除旧的快照图像
LANG=c snap list --all | awk '/disabled/{print $1, $3}' | \
while read snapname revision; do \
snap remove "$snapname" --revision="$revision"; \
done
漂白
一款出色的图形GUI工具，可满足所有需求：
sudo apt-get install bleachbit
删除手册页和文档
此外，您可以按照Ubuntu Wiki中的说明删除手册页和文档：
创建一个文件/etc/dpkg/dpkg.cfg.d/01_nodoc，该文件指定所需的过滤器。例：
path-exclude /usr/share/doc/*
# if we need to keep copyright files for legal reasons:
# path-include /usr/share/doc/*/copyright
path-exclude /usr/share/man/*
path-exclude /usr/share/groff/*
path-exclude /usr/share/info/*
# lintian stuff is small, but really unnecessary
path-exclude /usr/share/lintian/*
path-exclude /usr/share/linda/*
在项目配置的postinst中删除相同的文件和目录集。例：
echo "Removing documentation..."
# if we need to keep copyright files for legal reasons:
# find /usr/share/doc -depth -type f ! -name copyright | xargs rm || true
# else:
find /usr/share/doc -depth -type f | xargs rm || true
rm -rf /usr/share/man/* /usr/share/groff/* /usr/share/info/* /usr/share/lintian/* /usr/share/linda/* /var/cache/man/*
