Everything Linux

For IT leaders: Linux servers often run critical web, DNS, and file services, yet day-to-day knowledge tends to sit with one or two senior admins. That creates risk during outages, slows onboarding, and pushes routine work to contractors. Everything Linux helps spread that knowledge across your team.

Role fit: This intermediate course is best for Systems Administrators, IT Practitioners moving into Linux, and new admins a Team Lead needs to onboard. Coverage includes:

• systemd boot targets
• Users, groups, permissions, and special permissions (SUID and the sticky bit)
• Network and DNS troubleshooting
• BASH conditionals
• NFS file services
• Apache, Nginx reverse proxies, and BIND
• tmux and Rclone

Time investment: About 22.6 hours across 14 skills. Most skills run under two hours, so learners can fit them into normal work weeks.

Change-management note: This course is aligned to LPIC-2-related Linux administration objectives while still working well as operational upskilling. For teams with certification goals, Training Managers can pair it with related CBT Nuggets Linux certification training. Newer learners should start with the GNU and Unix Commands skill, because later skills build on standard input/output and file permissions.

How CBT Nuggets supports the outcome: Demos are designed for learners to follow along in a lab environment, so admins practice before touching production. Training Managers can use Playlists to assign only the skills a role needs, such as Apache and Nginx for web admins. Team Reporting lets you track progress across the group.

How this training helps your Linux team succeed in production

Everything Linux is built around the day-to-day work your systems administrators already handle: troubleshooting a server that won't resolve names, standing up web services, and automating repetitive tasks. Instructors demonstrate each skill at the command line, so IT Practitioners see the same steps they'll run in your environment.

• Faster network troubleshooting, less downtime. Your team walks through a real troubleshooting session with ping, ping6, traceroute, and tracepath. They also cover how the default route and gateway work and how to query local and remote DNS servers. Admins learn to find misconfigurations quickly instead of escalating them.
• Safer web service changes. Admins practice configuring and managing web services from the command line, including service behavior and common Linux administration tasks. That helps reduce accidental misconfigurations before changes reach production.
• Repeatable automation instead of manual work. BASH scripting moves from simple executable scripts to file tests, nested conditionals, and case statements. Your team can encode decision logic into scripts rather than relying on someone to remember each step.
• Consistent access control and boot behavior. Admins practice managing users, groups, ownership, and special permissions (SUID, SGID, sticky bit). They also learn to set systemd boot targets, such as switching a server to a command-line-only multi-user target, so every server follows the same standard.

The course also covers practical Linux administration topics such as storage, filesystems, privilege escalation, and command-line workflows. Team Leads can use it to bring new admins up to speed and fill gaps for experienced staff.

Knowledge

• How systemd boot targets relate to legacy run levels, including multi-user.target versus graphical.target
• How the Filesystem Hierarchy Standard organizes Linux directories, and where to look when troubleshooting
• How file ownership, permission strings, and special permissions (SUID, SGID, sticky bit) control access
• How pipes, data redirection, and xargs pass output between commands
• How DNS resolution order, the /etc/hosts file, and the default route affect connectivity
• How the Linux boot process starts services and daemons, including common services such as Apache and SSH

Ability

• Switch between boot targets and set the default boot target with systemctl
• Create and remove files and folders, use globbing safely, and edit efficiently in vi
• Add and modify users and groups, and change file ownership with chown and chgrp
• Write and run BASH scripts that use conditionals, nested if/elif logic, and case statements to automate tasks
• Troubleshoot network issues with ping, ping6, traceroute, tracepath, and DNS queries
• Configure Linux services and use tmux features such as configuration files, session locking, buffers, and window navigation
