Linux

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I rarely ever use the date command, but when I need it I almost always struggle to get the right incantation. So, wrote a blog post for easy reference.

Do you use a cheatsheet as well?

After a man date, I like to do a man touch and man mount.

Try the tldr util on linux.

[–] bobthecowboy@lemmy.world 7 points 3 months ago

I'm addition to tldr which someone else suggested, there's also the cheat command. It's pretty easy to add to it's cheat sheets, if you have custom commands, or want to keep a specific example. I've never kept a physical cheat sheet... They're just too inconvenient and my fingers are probably already at the keyboard.

Saving this post in case I ever get a date.

Thanks for posting this. Exmples are very useful.

LLMs do this pretty well. I've used them for date/time formatting strings across a number of languages.

They once wrote me a massive script for parsing a history file instead of telling me about history -i

The other "real person" who replied to me told me that the Linux date command has nothing to do with formatting.

[–] JackbyDev@programming.dev 2 points 3 months ago (1 children)

Second sentence of the description from the man pages, "Otherwise, depending on the options specified, date will set the date and time or print it in a user-defined way." not sure what they were on about.

Right - I'm just saying that it's super annoying that people point out times that llms have been wrong as though humans are never wrong, or even aren't wrong frequently.

[–] JackbyDev@programming.dev 1 points 3 months ago

I get that. It's funny I think I've gotten advice in the past to always check the results of search engines because they can be wrong (as in teachers said it to me) or things about Wikipedia being unreliable. But nobody does those things nowadays. Perhaps someday LLMs will be good enough that we don't need to check them either.
