I like people who write their own man pages with the most important information they keep forgetting about existing commands. Keep this info in text files and use a little script like `mman` to access those text files; keep using `man` for the original. I found this via tfurrows’s gopher site.
On Mastodon, I got some more suggestions:
@raucao suggested tldr. I installed the Perl variant via `cpanm tldr`.
alex@melanobombus:~$ tldr emacs
The extensible, customizable, self-documenting, real-time display editor.
✓ Open emacs in console mode (without X window):
🍣 emacs -nw
✓ Open a file in emacs:
🍣 emacs {{filename}}
✓ Exit emacs:
🍣 C-x C-c
Know about `ed` I can tell you that knowing how to quit is essential information. But surely there is more to it?
@coffe suggested cheat. I installed it via `pip3 install cheat`. And I set some options in my `~/bashrc`:
export EDITOR=emacsclient export CHEATCOLORS=true
You need to provide an editor because you can edit your cheat sheets. That’s the spirit!
The colourisation for the Emacs page is wrong. I guess it isn’t handled as Markdown? But at least there’s more information available. Perhaps it’s too much?
alex@melanobombus:~$ cheat emacs

I am reminded of my own recommendation regarding Emacs. I wrote this in 2006. Reference Sheet by Alex Schroeder (for Emacs).

I’ve done something similar using BASH functions. I first saw these in a comment on hackernews, and have simply taken them wholesale.
mdless() {
pandoc -s -f markdown -t man $1.md | groff -T utf8 -man | less
}
umedit() { mkdir -p ~/docs/linux_stuff/knowledge; vim ~/docs/linux_stuff/knowledge/$1.md; }
um() { mdless ~/docs/linux_stuff/knowledge/"$1"; }
umls() { ls ~/docs/linux_stuff/knowledge; }
However, these leave a little to be desired in terms of completeness. I’ve been mostly satisfied with them so far though!
