如何卸载Ubuntu中多余内核

http://blog.csdn.net/forlong401/article/details/6200877

1.使用这个命令可以查看当前系统使用的内核:

lee@lee:/$ uname -a 

Linux lee 2.6.35-25-generic #44-Ubuntu SMP Fri Jan 21 17:40:48 UTC 2011 i686 GNU/Linux

 

2.列出所有安装的内核，带有image的就是内核文件:

lee@lee:~$ dpkg --get-selections|grep linux 

libselinux1                    install

linux-firmware                    install

linux-generic                    install

linux-headers-2.6.35-22                install

linux-headers-2.6.35-22-generic            install

linux-headers-2.6.35-25                install

linux-headers-2.6.35-25-generic            install

linux-headers-generic                install

linux-image-2.6.35-22-generic            install

linux-image-2.6.35-25-generic            install

linux-image-generic                install

linux-libc-dev                    install

linux-sound-base                install

pptp-linux                    install

syslinux                    install

syslinux-common                    install

util-linux                    install

 

3.从中选择要卸载的包，用apt-get remove来卸载

lee@lee:~$ sudo apt-get remove linux-image-2.6.35-22-generic 

正在读取软件包列表... 完成

正在分析软件包的依赖关系树

下列软件包将被【卸载】：

  linux-image-2.6.35-22-generic

升级了 0 个软件包，新安装了 0 个软件包，要卸载 1 个软件包，有 0 个软件包未被升级。

解压缩后将会空出 107MB 的空间。
