Intro

Bellow follows a list of aliases, split between beginner and advanced.

To start using them right away you should place the aliases you like most in a file like ~/.zsh/git. Now all that remains is to add the following line to your ~/.zshrc or ~/.bashrc:

. ~/.zsh/git # git aliases

# newly created stacks should be empty
# after one push stack size should be one
# after one push and one pop should be empty
# when pushed past limit stack overflows
# when empty stack popped should throw underflow
# when one is pushed one is popped
# when one and two are pushed two and one are popped
# when creating stack with negative size should throw illegal capacity
# when creating stack with zero capacity any push should overflow
# when one is pushed one is on top
