Not a fan of the LLM-flavoured headings, and the tips seem like a real mixed bag (and it'd be nice to give credit specifically to the readline library where appropriate as opposed to the shell), but there are definitely a few things in here I'll have to play around with.

One thing I dislike about brace expansions is that they don't play nicely with tab completion. I'd rather have easy ways to e.g. duplicate the last token (including escaped/quoted spaces), and delete a filename suffix. And, while I'm on that topic, expand variables and `~` immediately (instead of after pressing enter).

My favourite shell trick is to comment my code:

  $ some_long_command -with -args -easily -forgotten # thatspecialthing

... Some weeks later ..

  $ CTRL-R<specialthing>

.. finds:

  $ some_long_command -with -args -easily -forgotten # thatspecialthing

Need to see all the special things you've done this week/whenever?

  $ history | grep "\#"

...

Makes for a definite return of sanity ..

Never heard of instant truncate, nor `fc`, nor `Esc .`

Quite a few useful ones

A much larger base for ksh (as a pdksh descendent) is Android. OpenBSD is a tiny community in comparison, although Android has acquired code directly from OpenBSD, notably the C library.

The vi editing mode is always present in ksh, but is optional in dash. If present, the POSIX standard requires that "set -o vi" enable this mode, although other methods to enable it are not prohibited (such as inputrc for bash/readline), and as such is a "universal trick."

The article is relying on some Emacs mode, which is not POSIX.

$_ is not POSIX if I remember correctly.

History in vi mode is easier, just escape, then forward slash (or question mark) and the search term (regex?), then either "n" or "N" to search the direction or its reverse.

I've seen a lot of people who don't like vi mode, but its presence is the most deeply standardized.

CTRL + W usually deletes everything until the previous whitespace, so it would delete the whole '/var/log/nginx/' string in OP's example. Alt + backspace usually deletes until it encounters a non-alphanumeric character.

Be careful working CTRL + W into muscle memory though, I've lost count of how many browser tabs I've closed by accident...

Also known as "emacs editing mode". Funnily enough, what POSIX mandates is the support for "vi editing mode" which, to my knowledge, almost nobody ever uses. But it's there in most shells, and you can enable it with "set -o vi" in e.g. bash.

With ctrl+r, if you press it twice, it will autofill the search with whatever you last searched for. pressing it more will go back through the history. Been using that a lot recently when doing docker stuff. ctrl+r, type the container name, keep going until I get the compose build command. ctrl+r, ctrl+r, repeat until the log command. Then I can just mash ctrl+r to get the build and log commands. Ctrl+r is your friend. ctrl+r

I love this, from a comment on the article:

  He had in his path a script called `\#` that he used to comment out pipe elements like `mycmd1 | \# mycmd2 | mycmd3`. This was how the script was written:
 
  ```
  #!/bin/sh
  cat
  ```

And not only cd. Gotta love 'git checkout -'

I just open, agent in tui, and ask it to do what I want and make a plan, i read the plan edit it and run it.

Simple, no need to learn any commandline these days.

I used to use arch and all, and managed many big projects. I find little value in learning new tools anymore, just feed it docs and it generated working plan most of the time

Now I've moved to coding in Haskell, which i find suits me better than wasting my time with cli and exploring what options all these cli tools have.

Using the terminal becomes much more cozy and comfortable after I activate vim-mode.

A mistake 3 words earlier? No problem: <esc>3bcw and I'm ready to go.

Want to delete the whole thing? Even easier: <esc>cc

I can even use <esc>v to open the command inside a fully-fledged (neo)vim instance for more complex rework.

If you use (neo)vim already, this is the best way to go as there are no new shortcuts to learn and memorize.
