# GRUB
|
||
|
||
| Commands | What it does |
|
||
|:--------:|:------------:|
|
||
| sed -i 's/^GRUB_CMDLINE_LINUX_DEFAULT="/&option /' /etc/default/grub | adds kernel option to GRUB file |
|
||
|
||
Replace &option with the kernel param like quiet or similar.
|
||
|
||
> *NOTE:* you will need to run this command when making changes to GRUB's file before rebooting:
|
||
|
||
```bash
|
||
sudo update-grub
|
||
```
|
||
|
||
Editing the /etc/default/grub file and changing the GRUB_DEFAULT line to match this will boot the previous kernel as the default:
|
||
|
||
GRUB_DEFAULT="1>3"
|
||
|
||
Run the update-grub command to save that change.
