Alias

What is an alias?

An alias is way to tell t-ui to interpret a set of characters as a proper command.

Why should this be interesting?

I usually try to ping google.com in order to check my internet connection speed:
ping -c 10 google.com
But it's really bothering to type everytime that long command. So I create an alias like "pg" (Ping Google):
pg=ping -c 10 google.com
Now, anytime I want to check my internet speed I can simply type "pg", instead of that long command.
