For those who didn't know: tldr is an actual command:

The tldr pages are a community effort to simplify the beloved man pages with practical examples.

It's a bash builtin, so none of these work anyway.

Oooh, neat. I didn't know about that. Thanks. That better not have been around since the 1990s or something, with me always searching the bash(1) man page to find builtin information.

$ help help|head -n2
help: help [-dms] [pattern ...]
    Display information about builtin commands.
$ git clone https://git.savannah.gnu.org/git/bash.git
$ cd bash
$ git log -S "Display information about builtin commands."|grep ^commit|tail -n1

Well, it's not the 1990s, but still. Dammit.

It gets complicated when using zsh.

I'm not complaining, much, but when my distro switched from bash to zsh and I didn't know until I reinstalled it for shins and gargles... that was a bad day for my remembered commands.

If you're not familiar, there's a chsh command.

That probably wasn't part of the upgrade process.

FWIW, most if not all bash builtins turn up when searching in man bash for [four spaces]command-name[space], but as someone else points out, the help command also er, helps.

Or you could read the info pages.

Maybe it's the (default) configuration on my distro, but info bash is the same information as man bash but with no bold text for headings and things. Ironically, I think I'd have to sit down with man info or info info for an hour or two before I could figure out how to get that formatting to show up in info.

Info pages are supposed to be way way more comprehensive than man pages. At least for the Gnu stuff since nobody else ever bothered with info (which can be painful to use for newcomers with the cli browser, although the kde help browser integrates info files flawlessly, of course).

That sign won't stop me, because I can't read!

$ man ls | spd-say -e

EDIT: If you run the above, it looks like speech-dispatcher splits the thing up into a bunch of different consecutive blocking requests, which means that it's a pain in the neck to stop with a single command. You might want to leave $ while true; do spd-say -S; done running for a bit to make it actually stop talking.

And then this happens:

~sh
$ command -h
Invalid argument

Context: I'm studying computer science.
When I notice my colleagues struggling with something on Linux, sometimes even getting desperate and asking AI, more often than not I manage to help or fix their problem by just reading the manual of the program they have trouble with.
