Also can use !! and do a space at any place to bring in last command. Not used much as you could just do an up arrow but helps if you edit around a lot and experimenting with a cli tool or command.

Unless you are looking to work on shared systems/servers as sysadmin or other jobs, explore shells like zsh or fish and customise them rather than stick to bash. A lot more user friendly and accessible advanced features. Helps with learning a lot. Zsh is compatible with bash but fish isn’t. So choose based on what your goal with learning shell is.

If you are sticking with debian based distros, try apt and synaptic(GUI) to install your software. At some point you might also need to install tar archives. Don’t get worried as most guides should be easy to follow.
