The touch command isn't actually for creating new files. It's for updating the access and modification times of the specified file or files. The fact that it creates the file if it doesn't exist is merely a convenient side effect.

Yes. You're right that the touch command didn't intend to create the new files, If files already exist then we can access & modification the file otherwise it'll create a new file

It's not a command, per se, but the up/down arrow functionality is something everyone should know. Toggles through previously entered commands. This is very handy if you're doing the same tasks several times over (avoids extra typing) and is helpful in reviewing what you've done in the event that it didn't work as intended.

And then you become addicted to it like me and press 11 times the up arrow to find back a ls :D

This is a good start, I would also recommend the following:

git
scp somefile sshuser@ip-address:/home/sshuser/
ssh sshuser@ip-address
grep
sed
tail
awk
htop
netstat -tupln --- sometimes you need to see what's holding up a port.
ps aux | grep python --- useful to find processes
kill -9 "process name" --- pair with above to kill a process that's misbehaving
nohup --- keep your script running even if there's a network disconnect
nice --- resource balancing for your scripts.

Agreed with @kwnaidoo, also it is good to understand the concepts of Redirections when using UNIX commands, that would be a good follow-up post of more advanced topics as well as using pipes like ps aux | grep python.
