Linux Command Line Masterclass with RHCSA & RHCE - 12 hours!

Learn to download the core utils source, inspect C code, modify main function, configure the compiler, and build and install using make and make install in an open source workflow.

Explore how software repositories act as libraries that enable automatic updates for a secure Ubuntu system. Learn the four repositories—main, universe, restricted, and multiverse—and their open or proprietary software distinctions.

Learn how apt-cache searches and shows package details from the local cache, explore the cache at /var/lib/apt/lists, and inspect packages like docx to text, Apache, and GCC.

Learn to manage software with apt-get: update and upgrade the cache, install packages, purge configurations, auto remove unused dependencies, and clean archives for a lean Linux system.

Learn how HPC software modules create software environments, using module load, unload, available, and list, plus man module for guidance.

Create a hello world bash script using vi, start with the shebang line, echo 'Hello World', make it executable, and run it with a relative path like ./hello_world.sh.

Explore using variables in a shell script by defining A and B and printing their values with echo and the dollar sign, producing Hello world, 640, and 7.2.

Explore arithmetic in bash by defining A=4 and B=3, using two open and close parentheses for A plus B, and echoing the sum and difference in a sample script.

Master bash conditionals in linux command line, using relational operators, if/else/elif, and string versus numeric comparisons to build practical, readable scripts.

Master bash loops in this lecture by building for and while loops, using range syntax, command substitution with backticks, and simple menus via user input and conditional logic.

Define and reuse shell functions to gather input with read and echo, and pass arguments to functions and scripts, including computing the square of a number.

Demonstrates linux command line scripting by defining shell functions to fetch IP address, system time, and username and host, then builds a menu-driven script that reads input and executes options.

Explore linux bonding to combine multiple network interfaces into a single, fault-tolerant, load-balancing bond. Learn bonding modes, kernel module setup, and practical configuration and testing for redundancy and throughput.

Master linux teaming with teamd, exploring runner modes like broadcast, round-robin, active backup, and load balance, using nmcli and teamctl to configure and verify on CentOS 7.

Deploy, configure, and troubleshoot firewalld on Red Hat 7 using firewall-cmd. Explore zones, how to open ports and services, and manage permanent versus runtime rules.

Master linux command line skills by configuring ipv6 addresses on two machines with nmcli, testing connectivity with ping, and inspecting ipv6 addresses, neighbors, and routes.

Learn to deploy and manage firewalld on Red Hat seven and sentell seven, using firewall-cmd to configure zones, services, and ports, and to persist firewall rules.

Learn to configure firewalld rich rules to control traffic, log events, rate limit, and implement port forwarding and masquerading using IPv4 NAT.

Install and secure MariaDB on a CentOS 7 system, start and enable the service, verify access with mysqladmin, and practice database creation, backup, and restore with mysqldump.

Configure a samba server on Linux by editing smb.conf and enabling the smb service, then create samba users and set up an anonymous share. Verify with testparm.

Master the Linux command line and root password concepts in a 12-hour RHCSA and RHCE aligned masterclass, focusing on secure password practices and administrative proficiency.

Attach an extra hard drive to an existing virtual machine by creating a disk image and adding it in the virtual machine's properties, then format and mount it.

Practice lvm by adding two disks, creating physical volumes, forming the Fiji pool volume group, creating a 3gb logical volume, mounting it, and extending vg and lv to 11gb.

Configure autofs to automatically mount home directories by setting up the autofs master and elder files, then start, restart, and test by logging in.

Add an extra 500 megabyte swap partition and mount it automatically at startup, without modifying the existing main partition. Enable swap on the new partition.

Configure the system hostname and network settings using nmcli, set IPv4 address, gateway, and DNS, activate the connection, and verify with ip a, host, and route.

Create a group named admin user and add Natasha and Harry as members, then create Sara with no login access; set passwords for Natasha, Harry, and Sara using their usernames.

Learn to use interactive playgrounds and run scientific codes in your browser with a free demo version, plus access a coupon from the extra contents; no registration required.

Develop Linux command line mastery through the RHCSA and RHCE masterclass, with a RHCSA practice exam video in this 12-hour course.

Master RHCE 8 skills with a one-hour practice exam video featuring Ansible, inside the Linux command line masterclass for RHCSA and RHCE.
