# Network-Usage-Tracker
2+
A python script to keep a track of network usage and notify you if it exceeds a specified limit
3+
(only support for wifi right now)
4+
5+
### Requirements:
6+
7+
#####**This script needs Python 3+**
8+
9+
You may also need to install vnstat if you don't have it already installed
10+
```bash
11+
$ sudo apt-get install vnstat
12+
```
13+
14+
### Usage:
15+
16+
```bash
17+
$ python bandwidth_py3.py xxx MiB/GiB &
18+
```
19+
The '&' has been added to run the process in background. If you want to stop the process at any time use :
20+
21+
```bash
22+
$ ps -ef
23+
```
24+
to get the list of running processes and then get the pid of the process you want to kill and do :
25+
26+
```bash
27+
$ sudo kill pid
28+
```
