Even after all these years, some people still have a strong dislike for systemd. My colleague, Umair, stopped hating systemd after realizing its automation capabilities.
He has created two courses on systemd:
- Systemd playbook: A hands-on, text-based course to turn you into a confident systemd user.
- Systemd automation: Learn to schedule, monitor, sandbox, and optimize automated workflows.
The best way to learn anything on Linux is by getting your hands on the system. That's the approach we take on Linux Handbook.
Other than us, here are several other platforms you can use to learn DevOps with practical, hands-on labs.
Basic but essential Linux concept: <, << and <<<
You'll often see <, << and <<< in various Linux command examples. It is important to know what they mean.
<: It is known asInput Redirectionand is used to take input from a file rather than typing instructions manually.<<: It is known asHere Documentwhich is used to provide multiple lines of input directly to the command.<<<: It is known asHere Stringand used to provide a single line of input to the command.
I know it sounds super complex but this article explains it in details.

💡Quick terminal tip
In Bash (and other Readline-based shells), navigating complex directories often means dealing with annoying typos or mixed case sensitivity. You can make Tab auto-complete paths regardless of capitalization while cleanly expanding common file prefixes before cycling through options.
Add these lines to your ~/.inputrc file:
# Ignore uppercase/lowercase differences during Tab completion
set completion-ignore-case on
# Treat hyphens (-) and underscores (_) as equivalent
set completion-map-case on
# Complete shared prefixes before cycling through individual choices
set menu-complete-display-prefix on
Now, if you have files named Project-Alpha.txt and Project-Beta.txt, typing cd pro and pressing Tab will first safely expand your prompt to the longest shared prefix (cd Project-). Pressing Tab a second time begins stepping smoothly through each matching file, completely ignoring letter case.

forgit: Interactive Git usage with fzf
Forgit is a shell utility that leverages fzf to provide interactive, terminal-native interfaces for routine version control operations. The tool integrates directly with CLI syntax highlighters while remaining lightweight and shell-agnostic across common terminal environments.
- ⚡ Fuzzy-search Git selectors with interactive diff and log previews
- 🌿 Interactive branch and worktree management for seamless switching
- 🛠️ Automated
.gitignoregenerator to fetch templates straight from your terminal - ⏪ Interactive rebase and fixup tools to easily squash and reorder commits
- 🎨 Extensible preview integration using external tools like delta for diffs and bat for syntax highlighting
