Covers foundational concepts including file permissions (chmod), variables, arrays, loops, conditionals, and functions. Also includes deploying an Nginx server, simulating a service incident, and using an AI agent for diagnosis while keeping manual control over fixes. Key takeaway: test both success and failure paths, and never trust anything blindly. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### why do I get permission denied when I try to run a bash script I just created A newly created file does not automatically have execute permission, so Linux blocks it from running. Grant execute permission explicitly with chmod +x followed by the filename, then run the script normally; without this step, attempting to execute it returns a permission denied error every time. _Developers hitting permission errors while learning bash scripting can find similar walkthroughs on daily.dev._ ## Similar posts on daily.dev - [Week 3 of My DevOps Journey: From Linux Commands to AI-Assisted Incident Response](https://daily.dev/posts/week-3-of-my-devops-journey-from-linux-commands-to-ai-assisted-incident-response-svrc7rsjm) · Medium · 0 upvotes · 0 comments - [5 hard lessons I learned in my first week on Linux, and I'm better off for them](https://daily.dev/posts/5-hard-lessons-i-learned-in-my-first-week-on-linux-and-i-m-better-off-for-them-unsns5bj3) · XDA Developers · 6 upvotes · 2 comments - [My Journey into DevOps: Learning Linux, Git, GitHub & My First Docker Container](https://daily.dev/posts/my-journey-into-devops-learning-linux-git-github-my-first-docker-container-bxhp3e0ci) · Medium · 145 upvotes · 25 comments --- Tags: [#devops](https://daily.dev/tags/devops), [#linux](https://daily.dev/tags/linux), [#shell](https://daily.dev/tags/shell), [#bash](https://daily.dev/tags/bash), [#nginx](https://daily.dev/tags/nginx) [View this post on daily.dev](https://daily.dev/posts/the-week-linux-humbled-me-in-a-good-way--4rdnvuf56) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"The Week Linux Humbled Me (In a Good Way)","url":"https://daily.dev/posts/the-week-linux-humbled-me-in-a-good-way--4rdnvuf56","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/the-week-linux-humbled-me-in-a-good-way--4rdnvuf56"},"datePublished":"2026-07-27T19:32:04.898Z","dateModified":"2026-09-14T08:42:02.675Z","description":"A beginner's reflective account of learning Linux and Bash scripting during week three of a DevOps cohort.
