Just taught me more than a $1000 uni course I took which was supposed to be about linux. It had a week or two about cli commands but was poorly taught. Uni of Toronto btw
At college, I was forced to learn about shell scripting, but after using Linux for more than half a year, I am enjoying every bit of it. I am still learning about shell scripting.
Goes from newbie to advanced real quick! I use the terminal a lot as a software engineer, but this taught me a couple things and I feel like I understand some things better.
I came here thinking I'm not a good enough wizard yet, but turns out most of these spells are already in my book. Learned some really wicked spells from this video!
fzf is really cool, gonna use it way more often from now on The only thing that I wish you'd also mention is how you can manipulate history too. Let's say you've done cat on some file with long path, and now you want to copy it. Instead of cp . you can do cp !!:1 . which will use first argument from latest command in history as argument. Also, cd (just cd, with no arguments) will send you to home directory and cd - will send you to previous directory.
currently taking a Linux class in college and this is was very helpful. I am already familiar with some the commands you showed but the short cuts and pipelines you showed were super valuable in making things easier!
I cannot express enough how much I needed this video. I just started a Systems class and my profs teaching style does not mesh well with my brain. THIS THOUGH!???! There is hope - thank you so much ❤
Impressed that you introduced me to a couple of commands I was not aware of and I pride myself in writing one liners that wrap 3 lines. Specifically `compgen` and `fd`. The latter of course written by the same fellow who's created `bat` which is wonderful replacement for `cat`. Another interesting way to use `xargs` is by inserting the output in a specific location in a command. e.g. $ aws ecs list-clusters | rg blah | cut -d / -f 2 | tr -d '",' | xargs -n1 -I{} aws ecs describe-services --services {} --cluster {} One I use fairly often while writing a long command where I need to switch to looking something else up is prepending the command with a `#` and hitting return, it parks the command as a comment which you can go back to editing but doesn't execute anything when initially entered. Try this in a chromium based browser with a ton of tabs open... `cmd + shift + a`... start typing the title of what you are looking for ;)
The xargs command section was really good! Something as simple as aliasing 'logs' to open a fzf with all your docker containers and choose one to check the logs for is just so useful
This is such a high quality video! It starts off great with some introductory concepts, but then accelerates at a great pace and shows how to put things together. Really was great for someone like myself who is comfortable in the shell but looking to level up. C-x C-e was literally a paradigm shift for me, and has changed how I interact with the terminal. Thanks for the awesome video, looking forward to more great content!
After watching this, it feels like you can do anything with the shell. Then you find yourself needing something like "pipe into a text file, but prepend instead of append", and it turns out you need to use four commands, invoke a function, write a formal proposal, and make a pilgrimage to Dennis Ritchie's final resting place on a moonless night and chant incantations from dusk to dawn to do it.
Haha yeah that is the sad truth. When you're within the bounds of what the shell and coreutils are good at everything is nice and simple. But once you step outside of that, it quickly feels impossibly complex.
Awesome video. Loved it. One of my favourite is 'seq'. Prints out a sequence of numbers. Handy and fast. Also one dirty trick to go to your home directory is only typing 'cd' and hitting enter. No need add ~.
Great video ! Btw in your node_module cleanup command you could put 2 inside the bracket of your cat command to get only the second part of the entry and not trying to cat the size of the folder like such: fd 'node_modules' -HIt d | xargs du -sh | sort -hr | fzf -m --header "Select which ones to delete" --preview 'cat $(dirname {2})/package.json' | awk '{print $2}' | xargs -r rm -rf
Nice video. I've been using Linux for 30 years and learned some new commands, such as fzf. One thing I would add is the tac command. It's cat but in reverse, which is sometimes handy
man works mostly only for coreutils, but not things like ripgrep, fd, fzf, jq etc, coz they don't usually provide it. So if you don't wanna google and your use case is trivial you could install tldr so it would provide some quick use examples. some OSes are POSIX compatible, but their commands could have different set of argument options. Same idea with subshell syntax, as well as advanced redirections. Also, if you forgot how to zip or unzip things using tar you can use mnemonic called "german voice" Compress Ze File -> tar -czf eXtract Ze File -> tar -xzf
@@hypnogri5457 because man uses specially formated text files located at certain places (man man can clarify the detes). When you install it from apt, aur, pacman or whatever else they usually do not provide those text files, so your only documentation located in under --help argument. So if it's works for you then someone made them for your OS distro.
at about 10:30: those are the emacs-like hotkeys for bash. dunno whether you can do that with zsh, but in bash you can change your mode to vi to get vi-like line editing
Can’t believe I’ve been using all these for years and never picked up on that! Feels bad haha. It looks like the set -o vi works in zsh too. Thanks for the tip!
This would be awesome as a downloadable PDF cheat sheet. ;) Excellent content on your page, easy to follow along and no annoying loud songs to distract. Sub'd. Hello from Canada!
When you started the video, it seemed like I am watching some noob tutorial, but in the last I became noob, 😂 you earned a subscriber, the knowledge you shared here is awesome, I will surely watch your bash scripting videos and other interesting linux related videos
Yeah, the biggest tip is to not try to remember everything. You naturally memorize things you use frequently, and for everything else, that's what documentation is for. On that note, / and ? are very important keybinds for many text viewers, as they let you search forwards and backwards. Very useful for finding relevant parts of manuals.
The dash can sometimes be used to use the previous value/location. "cd -" lets you go back to where you were. Nice if you cd into some root folder and want to go to where you were. Same goes for "git checkout -"; if you are in your branch, checkout to master to git pull, but want to return to the branch you were just in.
Wow, I thought I knew stuff in the terminal until watching this video xD. Thank you so much for sharing your knowledge with us, I'll make sure to implement this tips in my workflow
Been working in cli server for 2, years and I knew every command. I'd like to add 'history | grep "whatever"' for when you'd reuse some complex commands.
usually, rm -rf / will not run bc / is considered a device (because rootfs is mounted there), which cannot be deleted. rm -rf /* would still remove all system files, although you need sudo permissions to delete most of those, and some systems have safety nets for this specific use of rm.
"rm -rf /" will indeed not do anything but that is not related to it being misinterpreted as a device. It just refuses do execute this special case without being told to do so. It will happily delete everything below other mount points (some of which are usually the content of a device in the same was as the root filesystem).
I know I've used tail before when I needed to iter over a very large dir with an unknown amount of empty folders which would break another workflow. Amazing how fast it ran, just recursing through each level and nuking every empty dir it came across
11:02 The hotkey cheatsheet says ctrl-k “exits shell.” I believe this is intended to be ctrl-d which sends an EOF character. This will end any keyboard facing stdin. Am I missing something? I love this video. I’m pretty well seasoned with shell, but familiarity can get in the way of learning new tricks! Thank you for doing this.
My line editing became a lot less painful once I figured out I could use the emacs bindings on it. Also, I didn’t know about c-x,c-e which in retrospect makes a lot of sense. Thanks for teaching me something
I’m going to do my best to regularly forget to use fzf but also that last command with the open the editor was gold! But now I need to find the conf file to select the correct editor.
Haha I'm glad to hear it. The open the editor should default to using whatever you have set in your $EDITOR env var. So if you want to set that to nvim (or whatever you want) you can do: export EDITOR=nvim If you're using zsh, you can put it in the ~/.zshrc, if bash, it would be your ~/.bashrc -- if you're using something else, it'll probably be in a similar spot.
Shell - a program which sits between you and the kernel, needed to only pass legitimate, authorized commands to the kernel or other apps. Terminal Emulator - a program which emulates a vt100 terminal and escape codes. Terminal - previously a screen with a keyboard without any cpu or serious computational power, the device sent escape codes to the mainframe to administer it or just to work on the computer in general. Terminals were wiresly connected to the mainframe (usually in the same building). Console - a terminal (of 1970's) physically attached to the mainframe, other than physical attachment it's the same terminal. Today 'console' is often used in games, when you bring the terminal on half the screen, because it reminiscent of the old terminal attachment to the mainframe, so is a terminal attached to the game.
Shoot, you're right. Ctrl+D is correct, I scuffed the visual hotkey list. Darn, it doesn't look like there is a way to add an overlay in the YT video editor.
This is great, I’ve been using unix shell scripting a while but not wholeheartedly so haven’t really learnt it properly because i have extensive knowledge of powershell, even to the extent that install powershell on Mac and use it. But I realise that all the funky and fancy stuff in ps, I can do in way less code and probably more so just using the unix approach. Fzf is just fantastic and so is this video, you have given me inspiration to go head first into unix shell scripting so thanks 💪
I always wanted make a video like this Thanks for making it ( i can now peacfully sleep knowing that there exist a sensible video about shells and i dont have to procastinate about making one) Even tho i know all the stuff (except fzf preview one) i still enjoyed the video
if you think awk is confusing, you just haven't taken the time to learn it. It is an incredibly simple language that looks a lot like javascript. Literally just like like 15 minutes to read the documentation for gawk (in a browser, its just easier) and you will never be confused again
No worries, I didn’t take it that way. I appreciate the heads up. I use it often enough there is really no good reason to not spend a few minutes to actually learn it haha
To be fair, it's not that awk is that confusing. It's more like when you're initially learning all this stuff as shell utilities and then BAM out comes a fucking scripting language. One of these things is not like the other.
FYI - On fish shell press Alt+e instead of Ctrl-x Ctrl-e. Requires that you set the $EDITOR environment variable, You do that with set -gx EDITOR nano or whatever editor you wish to use. Put the set command string into your ~/.config/fish/fish.config file. The other keybinding is Alt-v which triggers the contents of $VISUAL instead of $EDITOR.
5:04 tail -f to follow appensions niice, 'tell u what; this vid is coming nice so far. not getting hung up in minute details but covering onteresting things which someone might be missing.
Thank you very much because I'm a noob in programming i barely use my linux mostly because I'm still struggling with learning my first programming language so I'll put all the tips into a written note on paper so when there's a need to use i can start using by accessing my external hard drive called paper while leaving my internal hard drive still struggling with learning programing
while it's cool to compose commands, for cleaning up files for space you really want to use a dedicated program, my current favorite in the terminal is diskonaut (but ncdu is nice as well and usually more available as a package). Both will crawl the entire tree from where you launch them and let you explore files interactively with visual aid for you to spot blocks of large files, they will also let you delete files along the way.
No one seems to cover export. I have exported local variables and they don’t seem to be applying toward a makefile. Says I have the wrong Python config version ...
Underrated, it's just amazing how serene and concise this video is

This is all pretty basic stuff for most *nix natives, presented excellently though!
Worth mentioning Ctrl-R as well for hotkeys. That fzf man alias is really cool

I am a self proclaimed shell wizard and learning sed can use any delimiter has blown my mind
That one is definitely a game changer.
I enjoyed this video. Pacing is nice.
Nice video! Well done explaining more than I thought I knew, so now I know more than I once did-eo..

shell wizard money gang we love casting shells
Sed also has sd (from cargo package manager)
Ah sweet, I knew about bat, but I hadn't heard of sd. Thanks for the heads up!
It looks quite nice (github.com/chmln/sd)
Oh, a useful cmd for kube pods is describe pods. Great for troubleshooting a pod in an error state.
That fzf is amazing.
Thank you very much because I'm a noob in programming i barely use my linux mostly because I'm still struggling with learning my first programming language so I'll put all the tips into a written note on paper so when there's a need to use i can start using by accessing my external hard drive called paper while leaving my internal hard drive still struggling with learning programing
while it's cool to compose commands, for cleaning up files for space you really want to use a dedicated program, my current favorite in the terminal is diskonaut (but ncdu is nice as well and usually more available as a package).
Both will crawl the entire tree from where you launch them and let you explore files interactively with visual aid for you to spot blocks of large files, they will also let you delete files along the way.
That is a good point. I’m familiar with ncdu, but diskonaut looks legit, thanks for the suggestion!
No one seems to cover export. I have exported local variables and they don’t seem to be applying toward a makefile. Says I have the wrong Python config version ...
other tutorials be like: "ok, now go to your root folder and then hack into the matrix mainframe so we can get started installing arch"
nice video 👏👏
((are you using the syne font? it’s my favorite! 0:26
