Like: |

sudo echo "sys-boot/grub:2 **" >> |
| 4 |
/etc/portage/package.accept_keywords/package.keywords.grub2 echo |
| 5 |
"sys-boot/grub:2 **" | sudo tee |
| 6 |
/etc/portage/package.accept_keywords/package.keywords.grub2 |
| 7 |
|
| 8 |

| 9 |
zjhui@gentoo ~ $ ls -l |
| 10 |
/etc/portage/package.accept_keywords/package.keywords.grub2 |
| 11 |
-rw-r--r-- 1 root root 0 Jul 1 10:37 |
