Wow I didn't realize !! is treated like an escape sequence, so it will expand even inside quotes (double quotes, but not single quotes). I can imagine someone going echo "hello world!!" and being very confused.

I actually had this happen to me early on when using bash.

one pro tip i use all the time is jobs. Ctrl+Z to suspend/pause the current shell command and then fg to get back to it. jobs to list all currently suspended commands.

Nice, some really good-to-knows there :) I also like Ctrl+p+q for detaching from an interactive docker container.

I think `Ctrl+Shift+u` for unicode is not Bash, but rather a GTK+ feature; which is where the shell session is running (inside a gnome-terminal, which happens to be GTK+). It also works in many other shells inside a GTK-based terminal, and further-more even in the web-browser. For instance, it doesn't work on Bash running inside Alacritty, and it works different on Kitty Terminal

indeed! a few have shown me this before as well

Should have mentioned this (coppied from bash(1)): operate-and-get-next (C-o) Accept the current line for execution and fetch the next line relative to the current line from the history for editing. A numeric argument, if supplied, specifies the history entry to use instead of the current line. Basically in bash, after doing a reverse search (C-r) you can run that command and get the next ready to run, and the next and the next... (possibly changing them before running) This is very useful.

afaik ctrl-shift-u is a Gnome-specific unicode entry mode. It works everywhere in Gnome, but not outside of Gnome.

Actually, it's GTK+ specific. It doesn't work, even inside GNOME, if the application is not GTK-based. For instance Alacritty or XTerm

Wow, very cool stuff :) didn't know about reverse-search. I always just grep on my history command, then use `!` for the entry I want to run. If I want to edit it I use `!:p`. Re: fc, I usually run `set -o vi` so I can run vi motions from the terminal, from there I can use `v` to edit commands. Nice post!

Absolutely love these kind of videos! Thanks :)

As always brilliant content !

Great video. Can I fork the wiki for the references?

I use mcfly as a ctrl-r extension. It’s recommendation algo and easy viewing of previous commands is really usefull

how to get out of the editor after the fc command?

@anthonywritescode

just quit the editor like normal -- (so if it's vim, you'd `:wq`, if it's babi you'd `^X`)

You're a total boss, dude! Your videos are gold!

I find it easier to memorize the ESC+ instead. Eg: ESC+. will write the paste the last argument. ESC+backspace will delete the last word. etc...

Alt+. will also produce the same effect, though the escape method allows you to fully press and release escape before tapping dot, etc.

it's the kinesis freestyle pro! here's my thoughts on it: kzread.info/dash/bejne/do6bpbeQlpyqirA.html

Reverse search (Crtl-r) is pretty universal. It works in python REPL, bash, zsh, PowerShell and many more. You can import prompt_toolkit and replace "input" with "prompt" and have your own reverse search. Its very easy: from prompt_toolkit import PromptSession session = PromptSession() while True: answer = session.prompt("Give me some input: ") print(f"You said: {answer}") if answer == "exit": break

^R is a readline feature -- all those things use readline when available (python on windows for example does not support it, and very frequently pyenv-compiled python doesn't either)

Ctrl+D doesn't work if the connection is stuck. For example if your wifi got disconnected while you were ssh'd into a server, neither ctrl+C or ctrl+D will do anything, you will have to close the terminal. But ~. worked to my surprise and it's a nice trick to know

if you compile them I'll put them into the description!

Ctrl + x then Ctrl + e opens the current terminal line in an editor, so similar to fc, but is better, because it works across multiple shells and together with history navigation is slightly more powerful.
