I also have a Windows blog but I am not asking anyone to follow or read it. I am not trying to promote myself but I am trying to promote OpenVMS. If you are a Windows administrator, you should learn about OpenVMS because a lot of Windows internals are easier understood when you see where they come from. If you are a Linux administrator, you should learn about OpenVMS to see how things can be done differerently and perhaps why they were done as you know it on Unix and Linux. ## Similar posts on daily.dev - [Day 10: File Permission Correction — Going Beyond rwx with Linux ACLs](https://daily.dev/posts/day-10-file-permission-correction-going-beyond-rwx-with-linux-acls-e8gdnbnsb) · Medium · 1 upvotes · 0 comments - [Old Windows quirks help punch through new admin defenses](https://daily.dev/posts/old-windows-quirks-help-punch-through-new-admin-defenses-srxzvyec2) · The Register · 0 upvotes · 0 comments - [Linux Equivalent to Group Policy](https://daily.dev/posts/linux-equivalent-to-group-policy-qoqudrvis) · apalrd's adventures · 0 upvotes · 0 comments - [Linux Capabilities Revisited](https://daily.dev/posts/linux-capabilities-revisited-34qqueksc) · Hacker News · 0 upvotes · 0 comments --- Tags: [#sysadmin](https://daily.dev/tags/sysadmin) [View this post on daily.dev](https://daily.dev/posts/wrote-a-blog-post-on-file-permissions-sizlsbqe3) ```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":"DiscussionForumPosting","mainEntityOfPage":"https://daily.dev/posts/wrote-a-blog-post-on-file-permissions-sizlsbqe3","headline":"Wrote a blog post on file permissions","text":"A community post links to a personal blog entry covering file permissions in OpenVMS using DCL, encouraging Windows and Linux administrators to learn OpenVMS concepts to better understand the historical roots and alternative design choices behind their own operating systems' permission models.","url":"https://daily.dev/posts/wrote-a-blog-post-on-file-permissions-sizlsbqe3","datePublished":"2026-09-29T19:02:21.100Z","dateModified":"2026-09-29T19:02:33.718Z","author":{"@type":"Person","name":"Andrew Brehm","url":"https://daily.dev/ajbrehm","image":"https://avatars.githubusercontent.com/u/48602082?v=4","description":"I am the least cool person you will ever meet.","interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"EndorseAction"},"userInteractionCount":1660}},"interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"isPartOf":{"@type":"WebPage","url":"https://daily.dev/squads/openvms","name":"OpenVMS"}} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"OpenVMS","item":"https://daily.dev/squads/openvms"},{"@type":"ListItem","position":3,"name":"Wrote a blog post on file permissions"}]} ```
