linux没有垃圾产生,但是会有一些无用的软件缓存文件,其删除缓存的方法是:1、通过“sudo apt-get autoclean”命令清理旧版本的软件缓存;2、通过“sudo apt-get clean”命令清理所有软件缓存;3、通过“sudo apt-get autoremove”命令删除系统不再使用的孤立软件。

Does Linux generate garbage?

本教程操作环境:linux5.9.8系统、Dell G3电脑。

linux有垃圾产生吗?

没有。

linux和windows系统不同,linux不会产生无用垃圾文件,但是在升级缓存中,linux不会自动删除这些文件,还是很占硬盘的!

一、删除缓存

1,非常有用的清理命令:

sudo apt-get autoclean                清理旧版本的软件缓存
sudo apt-get clean                    清理所有软件缓存
sudo apt-get autoremove             删除系统不再使用的孤立软件
Copy after login

这三个命令主要清理升级缓存以及无用包的。

2,清理opera firefox的缓存文件:

ls ~/.opera/cache4
ls ~/.mozilla/firefox/*.default/Cache
Copy after login

3,清理Linux下孤立的包:

终端命令下我们可以用:

sudo apt-get install deborphan -y
Copy after login

4,卸载:tracker

这个东西一般我只要安装ubuntu就会第一删掉tracker 他不仅会产生大量的cache文件而且还会影响开机速度。再软件中心删除。

附录:

包管理的临时文件目录:

包在

/var/cache/apt/archives
Copy after login

没有下载完的在

/var/cache/apt/archives/partial
Copy after login

二、删除软件

ubuntu软件的删除一般用“ubuntu软件中心”或“新立得”就能搞定,但有时用命令似乎更快更好~~

sudo apt-get remove --purge 软件名
sudo apt-get autoremove                                                        删除系统不再使用的孤立软件
sudo apt-get autoclean                                                            清理旧版本的软件缓存
dpkg -l |grep ^rc|awk '{print $2}' |sudo xargs dpkg -P              清除残余的配置文件
Copy after login

保证干净。

三、删除多余内核

1,首先要使用这个命令查看当前Ubuntu系统使用的内核

uname -a
Copy after login

2,再查看所有内核

dpkg --get-selections|grep linux
Copy after login

3,最后小心翼翼地删除吧

sudo apt-get remove linux-image-2.6.32-22-generic
Copy after login

ps:linux-image-xxxxxx-generic    就是要删除的内核版本

还有

linux-headers-xxxxxx

linux-headers-xxxxxx-generic    总之中间有“xxxxxx”那段的旧内核都能删,注意一般选内核号较小的删
