每次清理world file都要去找那一堆命令,之前找到英文版的在这里。
现在我将主要过程写在一个脚本里了，下次只要执行一下这个脚本就行了。
用wgetpaste贴在了这里。
主要会执行如下步骤：
代码:
echo "***********************************************" echo "The system will do the follow steps automaticly:" echo "1.cp /var/lib/portage/world ~ && >/var/lib/portage/world" echo "2.regenworld" echo "3.emerge --depclean -p" echo "4.emerge --depclean" echo "5.emerge -uDN world -pv" echo "6.emerge -uDN world" echo "7.revdep-rebuild" echo "8.eclean-dist -d" echo "***********************************************"
