Fix Your Shell Scripts With Shellcheck

[@fu_gyokuryu]

Weird world we live in, i found this today use it, and love it, and here it is DT doing a video on it

[@littlepeon]

was expecting your shell example to start with shebang: #!/usr/local/bin/fish But then i realized Shellcheck would respond with error message: warning! Fish is NOT a shell!

[@drishalballaney6590]

HAHA I am dying 🤣🤣

[@daringcuteseal]

loll

[@alexkeenan2575]

not sure if anyone gives a shit but if you are stoned like me during the covid times then you can watch pretty much all the new series on InstaFlixxer. Have been binge watching with my girlfriend for the last days =)

[@jaceisaac7379]

@Alex Keenan Definitely, I have been using instaflixxer for since november myself =)

[@RickRomig]

I've been using shellcheck for at least a couple of years. I've set up aliases with the options and exclusions I use. A very handy utility.

[@daxterstrock3319]

Actually really excited too use this as I’m learning to write my own bash scripts and such

[@martiniliev3021]

Thank you for this great utility, after checking with some scripts, I am impressed :)

[@kda_-uh3vj]

Amazing! I didn't know this existed

[@Gadgetoholic]

Really helpful. Thanks man!

[@AndersJackson]

The XML format is great for interpreting the errors in automatic testing software. Like CodeGrade or something like that.

[@zedth2]

or integrating it into some sort of text editor IDE

[@AtomToast]

you can also set up shellcheck with a diagnostics language server in order to get live linting right in your editor

[@swindlesmccoop]

do you know how i could set that up with vim?

[@henninb]

This is one of my favorite tools

[@rajughorai3909]

gone use next time i write shell code

[@jm1981]

Awesome stuff.

[@sasharenee252]

seems cool!

[@edupazz]

Great content, DT! Unfortunately, a downside of this application is it requires a ton of haskell dependencies (32, according to paru)

[@DistroTube]

If you have XMonad and Pandoc installed anyway (and you really should), then it isn't a problem. ;)

[@edupazz]

@@DistroTube it's no my case, indeed

[@BrucesWorldofStuff]

@@DistroTube HaHaHa I get 27 updates a day and 24 of them are Haskell updates and the sad thing. I don't remember why I have Haskell installed... LOL LLAP

[@AndersJackson]

@@BrucesWorldofStuff because you use Xmonad, of course. 😜

[@BrucesWorldofStuff]

​@@AndersJackson LOL... That's the thing! I don't use Xmonad... ROTF I do use Leftwm and Spectrwm.... (Ding) Wait! Wait! Got it! Leftwm had me install Xmobar, Lemonbar, and Polybar. But I never Xmobar or Lemonbar. I used Polybar instead... LMAO... I bet that's it... LLAP

[@MarcelRobitaille]

If you walk so much about how much more efficient window managers / keyboard-driven everything is you may want to leave insert mode from time to time (your rice is pretty nice though. Love the green status line).

[@SpencerA99]

checkbashisms is another good one. Also has a posix flag. Written by debian I believe

[@guilherme5094]

Nice!

[@YannMetalhead]

Good video.

[@lawrencedoliveiro9104]

2:38 Perfectly valid code so far.

[@tusharkuntawar6170]

Hey DT, do you know any stuff that makes navigation faster in vim without plugins

[@Neucher]

DT, what will be the requirement for DT OS install script? Will it work on a fresh arch ?

[@007arek]

What is the best alternative to bash except python? I'm looking something for writing scripts.

[@mantamizhan4305]

I would like know have you made terminal no-header ?

[@tazz7390]

Hey, DT, I have a question. How do you get menus for shutdown, restart and logout on window managers? I was using rofi before, but i3 doesn't seem to play well with rofi. Any suggestions?

[@tic-tech-toe5394]

you can use i3 menu to create custom menu for your likings. i am on i3 and i use that for shutdown and other custom shortcuts

[@twb0109]

Use i3 menus, they're like emacs keychords. Or write a shell script that outputs to rofi/dmenu, plenty of tutorials out there.

[@tazz7390]

Thanks guys, I'll try that out!

[@twb0109]

@@tazz7390 you're welcome

[@ricknaam5658]

I never knew this worked in emacs (just install flycheck and shellcheck, no config needed), Ive been copy/pasting into the website this whole time..

[@AndersJackson]

Hm, have to check that out.

[@aniakotowicz1976]

What are your thoughts on powershell core? 🤔

[@armynyus9123]

I have that rather directly in the editor: bash-language-server

[@lorenzocabrini]

I tried LSP mode and must say I was less than satisfied. I much prefer to run a linter after a CTRL-x s, rather than having Emacs doing weird stuff while I'm writing code.

[@armynyus9123]

@@lorenzocabrini I hereby admit kind of ashamed, that for coding I'm still on vim => did not try LSP in emacs. But yes, linting only on save.

[@lorenzocabrini]

@@armynyus9123 No need to feel ashamed. Nothing wrong about vim. It's a very capable editor. You could have done a lot worse, like some javascript-based freakshow. Sometimes it may sound like I criticize vim, but I really don't. what gets me is this very vocal minority of vim "users" who, instead of being happy with their own editor, go onto videos about Emacs and demand that Emacs should be like vim. I for one celebrate the fact that we have two very capable editors to choose from, that way I can have it my way and you can have it your way. I used a vi-clone called elvis for many years, so I'm quite familiar with vi keybindings. It's just that I personally prefer the Emacs ones, not because I think they are superior but merely because I'm really used to them for my everyday tasks.

[@phyzix_phyzix]

I was telling someone about this today. Nice coincidence

[@lawrencedoliveiro9104]

5:06 Not necessarily an error; it might be what you want.

[@auronkardek]

I gonna disable this double quote error really fast

[@lawrencedoliveiro9104]

3:38 Obvious problem at this point is the missing shebang line.

Hey DT! I made a comment which made reference to a shell script I wrote which is called "bench.sh" and that comment is gone. Did it go to spam, or did you actually delete it? I did not write anything which would warrant deletion --- however warrant or not, its ultimately you who decides what types of comments you want. At any rate, I have always been decent AFAIK so I'm perplexed as to why it was deleted. Greetings from Scandinavia! Have a fantastic day.

[@DistroTube]

Many comments get caught up in KZbin's spam algorithms. I don't see a comment from you in "Held for review". KZbin might have just deleted it entirely. Not much I or anyone else can do about this. It's just KZbin being KZbin.

​@@DistroTube I wrote a fairly long reply to yours just now and that too was deleted or "lost", unfortunately I had not copied and pasted the text into a texteditor as I normally do as a "security measure" or as a time saving effort when writing longer replies -- because the browser could crash and there goes the reply. So I have found myself automatically writing most of my comments in a texteditor simply to save myself time. But of course that does not rectify/fix anything when it comes to how YT handles comments -- its kind of just for my own sanity or peace of mind, because a guy's time is valuable as you probably already know very werll. At any rate, keep up the great content. I enjoy it all. 🙂

[@lawrencedoliveiro9104]

2:44 No such variable -- only error I can see so far.

[@lakromani8172]

Why does not shellcheck complain about the $sayHello? Line should be echo "$sayHello $myName"
