Linux System Administrator
Linux System Administrators keep fleets of servers running — managing systemd services, tuning storage and networking, hardening SSH and sudo policy, and automating patching with Ansible. Their daily English covers writing a change request for a kernel upgrade, explaining an inode exhaustion incident in a post-mortem, and documenting a hardening checklist for an audit. This path builds the foundational vocabulary that underlies DevOps, SRE, and infrastructure roles.

Vocabulary spotlight
4 terms every Linux System Administrator should know in English:
A background process that runs continuously without direct user interaction, typically managing a system service
"We restarted the daemon after the config reload flag failed to pick up the new certificate path."
A condition where a filesystem runs out of inodes — the metadata structures that track files — even though disk space remains free
"The deploy failed with "no space left on device" despite 40% free disk; it turned out to be inode exhaustion from millions of tiny log files."
A security principle where a user or process is granted only the minimum permissions needed to perform its function
"We tightened the sudo policy to enforce least privilege, so the deploy user can restart the app but not read other services' secrets."
Describes an operation that produces the same result no matter how many times it is run, a core property of good Ansible playbooks
"The playbook is idempotent — running it twice in a row makes no additional changes on the second run."

Recommended exercises
Real-world scenarios you'll practise
- Writing a change request for a kernel upgrade that explains the rollback plan if the new kernel causes driver issues
- Explaining an inode exhaustion incident in a post-mortem to engineers who assumed disk space was the only capacity concern
- Documenting an SSH and sudo hardening checklist clearly enough for an external auditor to verify each control
- Describing why a bash script needs to be rewritten as an idempotent Ansible playbook before it runs at scale

Frequently Asked Questions
What English skills do Linux System Administrators most need to improve?+
Linux System Administrators most commonly need to improve: technical vocabulary (the correct English terms for domain concepts), collocation accuracy (using the right verb for each action), written communication (bug reports, PR descriptions, technical docs), and spoken communication for standups, code reviews, and stakeholder meetings.
How long does the Linux System Administrator learning path take?+
The Linux System Administrator learning path contains 20–40 hours of material studied comprehensively. Most learners focus on the highest-priority modules first and return to the rest over time. Spending 30 minutes per day for 4–6 weeks produces noticeable improvement in workplace English.
What vocabulary should a Linux System Administrator prioritise first?+
Start with the vocabulary that appears most in your daily work — terms you read in documentation, use in commit messages, and hear in meetings. The Linux System Administrator path begins with the most frequent vocabulary clusters before moving to advanced communication patterns.
Are there interview exercises for Linux System Administrator roles?+
Yes. The Linux System Administrator path includes role-specific interview question modules with model answers and key phrases — the actual questions interviewers ask and the vocabulary needed to answer them fluently. There is also a dedicated Interview Practice hub for general interview skills.
Does this path include pronunciation help?+
Yes. The path links to pronunciation exercises for the technical terms most commonly mispronounced in this domain. The Pronunciation hub includes drills for acronyms, silent letters, word stress, and minimal pairs — all in IT context.
What are the most common English mistakes Linux System Administrators make?+
The most common mistakes: incorrect collocations (using the wrong verb with a technical noun), false friends from L1, tense errors when narrating past incidents or walkthroughs, and using overly formal or overly casual register in written communication.
How do I improve my English for code reviews?+
Learn the standard code review collocations: approve a PR, request changes, leave a nit, address feedback, block a merge, resolve a conversation. Use hedging language for suggestions: "This might be cleaner as…", "Have you considered…?". The Collocations section includes a dedicated Code Review set.
Can I use this path alongside my daily work?+
Yes — the path is designed for working professionals. Each exercise set takes 10–15 minutes. The most effective approach is to study a vocabulary module before a meeting or task where you'll use that vocabulary, then practise immediately after. Context-linked practice produces much faster retention.
Is the content free?+
Yes, completely free. No registration required, no payment, no time limit. All vocabulary modules, exercises, glossary entries, and learning path guides are open access.
How do I track my progress through this path?+
Progress is tracked in your browser's local storage — completed exercise sets are marked with a checkmark when you return. No account is needed. You can bookmark specific modules and use the exercises overview to see which sets you've completed.
