Cisco has some free Linux Training in Linux Essentials. Before you make the investment in a LPIC certification, this one would be a good place to invest your time. Thank you Cisco for providing this high quality free training.
Note, I am not an affiliate of this site, but I highly recommend their Linux Essentials Free course. I took this back in May 2019.
