Part 1: Ubuntu Users and Groups

Linux is a multi-user operating system. This means multiple people can be logged in and working on the same system simultaneously, and the system needs a way to differentiate their access.

1. Types of Users

Root User (Superuser):

The King/Queen: This is the most powerful user account (root). It has absolute, unrestricted access to the entire system.

UID 0: The root user always has a User ID (UID) of 0.

Bread and Butter Commands - all important

• This article provides practical examples of most frequently used commands in Linux/UNIX.

man - Super Important
cd ( Understand flags - dot ., double dot .., tilda~, dash -)
mkdir, mv
cp with recursive flag
ls with different flags
pwd, rm, sudo, apt
touch, cat, less, more
tail, rsync, grep
find - Super Important
sort, date, wc
tree (needs to be installed additionally)

Unix Intermediate commands

• lsof, kill, ifconfig
• chmod wget
• who whois
• Print user detail

# users name
who

# time of last system boot
who -b

Some Advance unix commands

• crontab, tail, Screen, grep, compress, wc

CRONTAB

• The crontab is a list of commands that you want to run on a regular schedule

# Shows all Crontab
crontab -l

# Edit Crontab
crontab -e

# Remove all cron tab --> Be careful
crontab -r

Command Line Basics Crash Course

Given above is a quick super-fast course in using the command line. It is intended to be done rapidly in about a day, and not meant to teach you advanced shell usage.

1.1 What is version control?

• Version control is a management system that allows you to record and track changes in your source code and files so that you can recall certain versions later.
• It’s like a Google Doc for programming, where you can collaborate with multiple people working on the same code and see the source code’s history

Ultimately, using a version control system allows teams to streamline their development process, which improves their overall efficiency

Git Standard Practices

1. Using .gitignore

Useful .gitignore templates: GitHub

The .gitignore file is a text file that tells Git which files or folders to ignore in a project. A local .gitignore file is usually placed in the root directory of a project. You can also create a global .gitignore file and any entries in that file will be ignored in all of your Git repositories.
