Download linux on your computer(Mint or Ubuntu id recommend). Then look up the basic commands and use them (ls, cd ...). Then move on to making your own aliases(search up 'making bash aliases'). By this point you can now start trying some more advanced things like having aliases which start up programs and open your project folders(search up 'dotfiles bash'). Lastly learning some shell script can help you better understand and utilize the terminal(as you can write complex shell scripts for your aliases). As a side note using vim(or emacs) as your default text editor will keep you in the terminal longer helping you get used to using it.
