# 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.
