To make your life easier and reduce the amount of commands you have to type, you can use aliases!
Open a Terminal and type:
Once .bashrc opens in leafpad, scroll to the bottom of the document and add
# My Aliases
Next its time to add aliases. you have to add them each on their own line below the my aliases comment you just added. Don't forget to save your file after you're done adding aliases. Remember you will have to open a new Terminal to use your new aliases.
The correct syntax for creating aliases is:
alias youralias =' the command to execute '
So for example:
alias get='sudo apt-get install'
In Terminal you just type: get firefox and due to this alias the cli will execute sudo apt-get install firefox.
One more example:
alias remove='sudo apt-get remove'
In Terminal you just type: remove firefox and this will execute the following command: sudo apt-get remove firefox.
