Auto create screen at startup

[Ashaxer]

Hi. since I am using my servers for other purposes too, I reboot it frequently, so I made a piece of bash command to create a crontab schedule to start an screen at every startup of my server.

This code creates an screen with name lava and starts the task:
screen -dmS lava sh -c 'cd /root/lava-farmer/ && go run main.go'

This code is supposed to be added to crontab schedules like this:
crontab -e
and adding this to the file and save:
@reboot screen -dmS lava sh -c 'cd /root/lava-farmer/ && go run main.go'

And this final code automatically adds the above code to crontab schedules all at once:
{ crontab -l -u root; echo "@reboot screen -dmS lava sh -c 'cd /root/lava-farmer/ && go run main.go'"; } | crontab -u root -
