How to avoid long commands and mistypes?

The alias command is useful for setting up shortcuts for long commands, or even more clever things.



But there are other uses of alias. For example, common mistyping mistakes. How many times have you accidentally left out the space when changing to the parent directory?



Alternatively, how about rewriting some existing commands?



To have these shortcuts enabled for every session, just add the alias commands to your user .bashrc file in your home directory.
