Start a terminal and make sure you use bash as a shell. I think bash is default in Mint?! Now, while being in terminal, you press the tabulator key twice.
As an output you have ALL terminal commands (n such) without the shell buildin commands. But these commands can be found in the shells manpage. Start with an man man to get familiar with the use of manpages and then go for man bash (n such) to dig deeper into the wonders of the shell.
Have fun!
