Bash script to run on the first time working with a raspberrypi, (installs nodejs, npm, chromium-browser, noip, and sets a static ip)

A better solution than screen is tmux. To launch something as a service you can use
sudo nano /etc/systemd/system/tswira.service

service looks like this:

[Unit]
Description=Run tswira_follow_likers.sh on startup in tmux
After=network.target

[Service]
Type=oneshot
ExecStart=/bin/bash -c "sleep 30 && sudo -u pi tmux new-session -d -s tswira_session '/home/pi/Desktop/archive/ig_bot_selenium/bash_scripts/tswira_follow_likers.sh'"
RemainAfterExit=true

[Install]
WantedBy=multi-user.target

Reload and enable the service

sudo systemctl daemon-reload
sudo systemctl enable tswira.service

** (Optional) Start it manually to test**
sudo systemctl start tswira.service

Check status or logs

sudo systemctl status tswira.service
journalctl -u tswira.service
