apt configurations are located in /etc/apt/ following is a breakdown for the different directories

Main Components

1. sources.list: This is the main list of repositories that APT will use for software package management. Each line in this file specifies a different repository. Ref: man 5 sources.list

2. sources.list.d/: This directory allows you to add additional repository lists without modifying the main sources.list file. Each file in this directory should end with .list and contain one or more repository lines, just like the main sources.list file. Ref: man 5 sources.list

1. Simple Assignment (=):

   • It assigns a value to a variable.

   • The value of the variable is evaluated when the variable is used, not when it's declared.

   • This means that if you reference other variables in the assignment, their values will be expanded at the time of use, not at the time of assignment.

     FOO = $(BAR)
     BAR = Hello
     all:

@echo $(FOO) # This will output "Hello"

# One could use vimdiff, meld, or even diff
def diff_with(test_func=None, tool='vimdiff'):
    # The decorator was used with parentheses
    # thus the test_func is not set, we need to call it ourself
    if test_func is None:  
        return functools.partial(diff_with, tool=tool)
