草际鸣蛩 惊落梧桐:删除不用的Ubuntu Linux旧内核文件

用上Ubuntu Linux后就没重装系统过！在经过多次升级更新后，系统里会积累多个Linux内核文件，而旧内核并没被自动删除！也就导致启动时有很长的内核列表可选择，动手删了它。
一、查看系统当前使用的内核：

终端输入：uname -a¹ [查看更多帮助：uname --help]

1 2 miao@miao-laptop:~$ uname -a Linux miao-laptop 2.6.35-23-generic #41-Ubuntu SMP Wed Nov 24 11:55:36 UTC 2010 x86_64 GNU/Linux

二、列出所有安装的内核：

终端输入：dpkg –get-selections | grep linux

01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 miao@miao-laptop:~$ dpkg --get-selections | grep linux libselinux1                 install linux-firmware                  install linux-generic                   install linux-headers-2.6.32-21             install linux-headers-2.6.32-21-generic         install linux-headers-2.6.32-22             install linux-headers-2.6.32-22-generic         install linux-headers-2.6.32-23             install linux-headers-2.6.32-23-generic         install linux-headers-2.6.32-24             install linux-headers-2.6.32-24-generic         install linux-headers-2.6.32-25             install linux-headers-2.6.32-25-generic         install linux-headers-2.6.35-22             install linux-headers-2.6.35-22-generic         install linux-headers-2.6.35-23             install linux-headers-2.6.35-23-generic         install linux-headers-generic               install linux-image-2.6.32-21-generic           install linux-image-2.6.32-22-generic           install linux-image-2.6.32-23-generic           install linux-image-2.6.32-24-generic           install linux-image-2.6.32-25-generic           install linux-image-2.6.35-22-generic           install linux-image-2.6.35-23-generic           install linux-image-generic             install linux-libc-dev                  install linux-sound-base                install linux1g1g                   install pptp-linux                  install syslinux                    install syslinux-common                 install util-linux                  install

注：上表中带有image的是内核文件

三、删除内核:

1 sudo apt-get remove 内核名

注：带有image的文件是需要删除的，一定要写全版本等字符,其他相关的文件会自动删除。
