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 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
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!
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.
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.
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 + 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.
@@anthonywritescode I did, but missed the mention of it also missed the Alt + . (dot) the first time. Just spaced out. At least the info that it works in shells other than bash was not in the vid ;D
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
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.
heh and this is why I almost always use hard-quotes (single quotes)
hah, quite the gotcha indeed
Or trying to do a commit with the inline message "Done!!"
I actually had this happen to me early on when using bash.
Nice, some really good-to-knows there :) I also like Ctrl+p+q for detaching from an interactive docker container.

indeed! a few have shown me this before as well

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

Hi anthony, FYI, you typed your password while recording your keyboard ...
I think he uses a virtual machine to make videos so it doesn't actually matter : }
yep -- my password is literally "bad password"

ctrl+. for emoji chart or tabel ,
unlike ctrl+shift+u youdont have to remember the unicode value
😉
doesn't work on linux or windows -- must be a mac specific thing
Cool keyboard, what is it?
it's the kinesis freestyle pro! here's my thoughts on it: ruclips.net/video/DZgCUWf9DZM/видео.html
`y` does work on gitlab. Unfortunately know this from experience.
you poor soul, gl with your choo choos
@@anthonywritescode "run train is against our coc"
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?
just quit the editor like normal -- (so if it's vim, you'd `:wq`, if it's babi you'd `^X`)
Absolutely love these kind of videos! Thanks :)
Great video. Can I fork the wiki for the references?
You're a total boss, dude! Your videos are gold!
Timestamps would be very much appreciated. 🤙
if you compile them I'll put them into the description!

@@anthonywritescode Just checked both cmd and new Microsoft Terminal on windows and reverse search works in python with no problem.
you must've installed readline -- the official distributions do not come with functioning readline
@@anthonywritescode You are right, I installed pyreadline. Forgot about this module
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...
I assume you map capslock to control, otherwise those are quite the stretch!
Alt+. will also produce the same effect, though the escape method allows you to fully press and release escape before tapping dot, etc.
you can also do control-[ + . as well
^r is a great one thanks ! There was me doing history | grep git all this time

you can use ctrl - D instead of ~. to close ssh connection. Or get out of the attached docker container terminal

nope! ~. is specifically needed when the session is stuck and you want to forcibly detach
Title should have been useful bash tricks I wish I knew
not all of them are bash
