I want to share a simple, but very useful hint for your aliases, which I noticed in 
gark87Task:Make sure that all your shells have the same aliases, and that when adding a new one, you don't have to edit a bunch of files.
Decision:1. We take out all alias to the file 
~/.alias2. In ~ / .bashrc, ~ / .zshrc, etc. write: 
. $HOME/.alias # there is a dot and a space before $ HOME
