Rules for Posting Guides on Our Community

1. Defining a Guide Guides are comprehensive reference materials, how-tos, or comparison tables. A guide must be well-organized both in content and layout. Information should be easily accessible without unnecessary navigation. Guides can include flowcharts, step-by-step instructions, or visual references that compare different elements side by side.

2. Infographic Guidelines Infographics are permitted if they are educational and informative. They should aim to convey complex information visually and clearly. However, infographics that primarily serve as visual essays without structured guidance will be subject to removal.

3. Grey Area Moderators may use discretion when deciding to remove posts. If in doubt, message us or use downvotes for content you find inappropriate.

4. Source Attribution If you know the original source of a guide, share it in the comments to credit the creators.

5. Diverse Content To keep our community engaging, avoid saturating the feed with similar topics. Excessive posts on a single topic may be moderated to maintain diversity.

6. Verify in Comments Always check the comments for additional insights or corrections. Moderators rely on community expertise for accuracy.

Cool though still a bit confusing, like what's a "Device file"? Also so many of those are so similar in use like /usr and /sbin. Why would one be used over another?

[–] [email protected] 3 points 1 month ago

/sbin is like /bin, but for system administrative type commands. /usr holds all the other software that isn't critical to get the system up and running.

A device file is a special file that's like a pointer to a piece of actual hardware, like a serial port or a hard drive. /dev also has some non-hardware special files like /dev/zero. When you read from that one, you get an endless stream of zeros. Or /dev/null, that discards any data that's written to it.
