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.

What's your favorite well-designed CLI and why? (lemmy.world)

Regardless of what the app does and whether the thing that does is particularly useful, powerful or important for what you need to do (or even well implemented), what is a command-line interface that you had a particularly good experience both learning and working with?

In other words, I'm thinking about command line interface design patterns that tend to correlate with good user experience.

"Good user experience" being vague, what I mean is, including (but not limited to)

discoverability--learning what features are available),
usability--those features actually being useful,
and expressiveness--being able to do more with less words without losing clarity,

but if there's a CLI that has none of those but you still like it, I'd be happy to hear about it.

Edit: Trying to stress more that this post is not about the functionality behind the tool. Looks like most of first responders missed the nuance: whether app x is better than app y because it does x1 ad x2 differently or better does not matter; I'm purely interested in how the command line interface is designed (short/long flags, sub-commands, verbs, nouns, output behaviors)..

No problem, it's always good idea to ask.

By convention two dashes -- are used for options with long name, such as --remove, while single dash - is used for single letter options such as -R. There can be some extra rules how options are used and combined, but that is not always true for every application. A common implementation is that options with single dash can be combined to have less to press, while double dash options cannot. Meaning if you have options -a -b -c then you could combine them into one bucket as -abc or -ab -c, all equivalent. But you cannot combine --remove -a -b into --abremove in example. There can be some extra rules and some applications handle options bit differently.
