running stuff in the background at a specified time is awesome
I forget to backup my files and so i use cron to do it for me.
Here is a basic rundown-
crontab -e
it will ask for setup, use your favorite editorexport EDITOR=nvim
now run crontab -e
again and you should be able to access the file
# Add this line to your crontab file to run the backup every day at 2 AM
0 2 * * * rsync -ah --info=progress2 /path/to/source /path/to/destination
those asterics are wildcards! It means run it everytime
use this command format examples for cronjobs
