# Update
|
||||
|
||||
Update script written in bash for Arch. Keeps all your pacman and aur packages as well as your flatpaks up to date with one simple script. It also backups a list of all your pacman/aur pkg's and flatpaks. As well as your fstab and the makepkg.conf to the location that you specify in the config.

Update script written in Bash for Arch Linux only. Keeps all your pacman and aur packages as well as your flatpaks up to date with one simple script. It also backups a list of all your pacman and aur packages and flatpaks.

## Requirements
|
||||
|
||||
Here is what is required.
|

|
||||
Doing that would look like this.
|
||||
```bash
|
||||
ln -s /usr/bin/your_program /usr/bin/sudo

||||
```
