CentOS8：删除多余内核

CentOS8：删除多余内核

 

 

 

 

一、删除内核方法：

 

[root@rocky tmp]#  rpm -qa | grep ^kernel;  rpm -qa  |grep ^kernel  |grep -E -v `uname -r`  |xargs  rpm  -e  --nodeps

[root@rocky tmp]# echo "-- BEFORE --";rpm -qa | grep ^kernel;  rpm -qa  |grep ^kernel  |grep -E -v `uname -r`  |xargs  rpm  -e  --nodeps;  echo "--- AFTER ---";  rpm -qa | grep ^kernel

 

 

 

 

二、示例：
