One of the best ways to run scripts on boot in Linux by using systemd.

Scraping a website is easy, but have you ever wondered how one can scrape PDFs? Especially tables? Here's what I learned and discovered.

Sometimes one may wish to run scripts at boot. I looked at a lot of solutions including crontab but the only solution that worked for me was systemd. This can be done for all Linux systems but since I did this on the Raspberry Pi I have included it here.
We will be creating a .service file in /usr/lib/systemd/system.
This will be followed by sudo nano /etc/systemd/system/discord-webhook.service. In the file you will include the following lines of code
[Unit]
Description=Discord Webhook IP sender
[Install]
WantedBy=multi-user.target
[Service]
ExecStart=python /bin/main.py
Type=simple
User=pi
Group=pi
WorkingDirectory=/bin
Restart=on-failure
Once done hit Ctrl+X followed by Y and Enter
Before actually starting the service you may want to ensure that you have the main.py code. Here is the code (you may change it to your needs)
Run this - sudo nano /bin/main.py
import socket
import requests
import urllib.request
webhookURL = '<webhook url>'
hostname = socket.gethostname()
external_ipv6 = urllib.request.urlopen('https://v6.ident.me').read().decode('utf8')
external_ipv4 = urllib.request.urlopen('https://v4.ident.me').read().decode('utf8')
data = {
'username': 'Server IP Webhook',
'embeds': [{
'title': 'Server started!',
'description': hostname + '\n' + 'IPV6' + ': ' + '`' + external_ipv6 + '`' + '\n\n' + 'IPV4 ' + ':' + '`' + external_ipv4 + '`',
}]
}
result = requests.post(webhookURL, json = data)
try:
result.raise_for_status()
except:
pass
sudo systemctl daemon-reloadsudo systemctl start discord-webhook.service (if there is an output then your code is functioning successfully!)sudo systemctl enable discord-webhook.serviceAnd you're good to go! Your script will now run at startup!
