I can't believe you showed how to create aliases with the command line, specified that it will be deleted if the system is switched off (see * note below about this) and don't even tell how to add them to the .bashrc to make them permanent.
The user's .bashrc (or the .cshrc if you use tcsh) is loaded every time you launch a terminal, so if you open the file with nano or vim (nano ~/.bashrc), add the alias line to it and save the file, every time you will open a new terminal the line will be executed and you will have your alias ready to be used. If you want it to be available in the current terminal (the one you used to edit the. bashrc), just type
source ~/.bashrc
*aliases created with a command line are actually only defined in the terminal in which they get created and will be deleted if you close this terminal, not only after a system shutdown.
