# Topgrade wrapper
**Linux bash script** for cronjob using **notify-send** to show a notification to the main desktop user when topgrade starts and ends.
* The notification disappears after a few seconds if everything is OK or
* stays until you click on the error message.
So you stay informed if something goes wrong.

## 👉🏼 Requirements
* Linux
* topgrade
* sudo permission for your desktop user (for topgrade)
* notify-send (topgrade will start if it is not installed - but then you won't need this wrapper)
## 🖥️ Installation
Extract a downloaded archive in `/opt/` or better use `git clone`.
As root:
```txt
cd /opt
git clone https://github.com/axelhahn/bash-topgrade-wrapper topgrade-wrapper
```
No configuration is needed.
## 💡 Usage
### ⌨️ Interactive test
For a first test in a terminal start the script with **your user**.
```txt
/opt/topgrade-wrapper/start_topgrade.sh
── 22:04:37 - System update ────────────────────────────────────────────────────
Warning: Building packages as dynamic user
Warning: Setting build directory to /var/cache/pamac
Preparing...
Synchronizing package databases...
(...)
```
You should see a disappearing notification box as well:
If the script ends you get a notification again.
* It is a disappearing notification on success or
* an error message on failure that stays on the screen until clicking on it.
### 👹 Troubleshooting
`topgrade`is started without sudo.
On my Manjaro installations it asked for a password even if my user had sudo to all commands without password.
Solution: The installer `pamac`on Manjaro uses polkit. To allow pamac passwordless actions create a file **/etc/polkit-1/rules.d/99-pamac-override.rules**:
```txt
/*
* source: https://forum.manjaro.org/t/how-to-override-polkit-password-prompt-in-pamac/151774/2
*/
polkit.addRule(function(action, subject) {
if (action.id == "org.manjaro.pamac.commit" && subject.isInGroup("wheel")) {
return polkit.Result.YES;
}
})
```
### 🕓 Cronjob
Create a cronjob eg. as file in `/etc/cron.d/`.
In your cronjob
* Execute the wrapper script as user that has sudo permissions
* Redirect the output
**Example**:
```txt
50 8,12,16,20 * * * axel /opt/topgrade-wrapper/start_topgrade.sh >/tmp/topgrade.log 2>&1
```
OR
When starting the job as root
* Add a variable `SUDO_USER=` to set a target user for notification
```txt
SUDO_USER=axel
50 8,12,16,20 * * * root /opt/topgrade-wrapper/start_topgrade.sh >/tmp/topgrade.log 2>&1
```
I prefer my **Cronwrapper** to simplify monitoring all cronjobs
📗 Docs: see https://www.axel-hahn.de/docs/cronwrapper/
Then it can look like this:
```txt
50 8,12,16,20 * * * axel /opt/cronwrapper.sh 1440 "/opt/topgrade-wrapper/start_topgrade.sh" 'os-update'
```
