I was recently watching a video that was walking beginners through terminal commands and they listed over 50 commands that you should use. 50!? Who uses more than 10 terminal commands?
The ones that I use (off the top of my head)
clear will... you guessed it, clear your terminal.
There are some special options that you can pass into some of these commands but for now, the basics are all that is needed to be a hacker!
Some honorable mentions - these are commands that I use here and there.
mv- move files or rename files
sudo- "SuperUser Do", this enables admin/root permissions, only use this if you know what you are doing
grep- search for something in a file
ping- check your connectivity status to a server.
echo- used to move data into a file
