## has_update
This tool is used to check - with a set registred project - for:
- available online latest version
- current installed version

This tool, written in python and under GPLv3 Licence assumes project is
installed using git in an admin project name owner on the system.

It is configured here for "mastodon" project, but you can copy and use it,
by changing the settings inside the script

```
owner = "mastodon" # Also used for sudo -u {owner}
name  = "mastodon"
repo  = f"https://api.github.com/repos/{owner}/{name}/releases/latest"

```

### Installation
```
cd /srv
git clone https://forge.a-lec.org/cominfra/toot.git
chmod +x toot/tools/has_update
```

### Usage
```
Usage: has_update [argument]
   -h  : This help !
   -v  : Show both versions (online, and installed)
```

This tool is intended to inform administrator about available update of a
project. You can use it with an external script in a crontab that checks the
ouput of *has_update*. Do not forget, in that case, to not give argument. With
no argument, *has_update* ouputs a message ONLY if an update is available.

```
cd /home/mastodon/live
/srv/toot/tools/has_update
```
