centos更新了内核，出现两个选项

[yinznet]

centos更新了内核，grub启动出现两个选项，进去好像都是一样的，怎么删掉一个呢？

[octopus_new]

#rpm -q kernel //will list all kernel including current kernel

#uname -a //check the kernel name

#rpm -e [kernel name] //remove the kernel which is not use anymore.

#package-clean --oldkernel --count=1

上面，错了！

#package-cleanup --oldkernels --count=1

上面两位都命令不一样，看不懂啊
