Ok, your format and pace is outstanding. One suggestion for people like me looking for this type of content. Expand on your "one video" trademark, experiment a little. I don't know if longer videos actually get less playtime, but it is known that RUclips's content gets shorter and shorter as people's attention spans are changing. Don't conform to this. Capitalize on the "in one video" thing and maybe add a unique hotword to them (fastpace synonym - something catchy). Man this video style is just great for me, you got a new sub and I'm sending your channel to everyone who wants to learn fast. I rarely comment on videos but had to let you know this is special here. Just gotta promote the brand if your other videos are similar.
I need to hit stop every time somebody says anything to me and rewind a bit, but in a good way, as said it cultivates focus. (this pace with this type of presentation works well, this pace if part of a general concept/explanatory lecture would not be recommended.)
I usually watch these videos at 1.5x or 2x speed and also use the cheatsheet as a guide and i find that works for me to quickly go through these videos.
VIM Cheat sheet (based on video, thanks to Derek) • "Shift +a" (Upper case A) put you in insert mode • "Shift + g" (Upper case G) will let you go to last line • Pressing "o" will move you to next line in insert mode after "Shift + g" • "w" move forward to next word (first char of word) • "b" move backward to last word (first char of word) • "0" (zero) beginning of the line. "$" end of the line • Global settings like syntax on, autoindent can be saved in vimrc file, located in user home directory. This will make them permanent as well. • "Shift + v" (Upper case V) will select the line, use arrow key to select more. "v" will select the character. • "d" to delete (or cut) the text. • "y" to copy • "p" to paste • "u" to undo • Press Esc for command mode type ":" and commands ○ q! -: Quit without saving ○ wq -: Save and quit ○ set number -: will display the line numbers ○ syntax on -: Will show syntax highlighting ○ set tabstop=2 -: Set tab space to given number ○ set autoindent -: for auto indent new line

Just starting an internship in 3 days, and they emailed me to "brush up" on linux shell scripting. I've never done it and I'm not sure why they think I have. I finished this video, and it has been hugely helpful! Just a lot of densely packed information so I will probably watch it a couple more times. Thanks a bunch, super helpful!
Subscribed to you a long time ago because of your great tutorials, but I haven't made the time to watch any of your videos in a real long time. Saw this, and I'd been wanting to learn BASH scripting, and I remembered again why I subscribed. You have the best programming tutorials online bar none, and I really need to spend the time investing in myself by watching more of your videos! Thanks so much!
correction 53:20 - indirect refferencing using ' ! ' is how to print out indexes for i in ${!fav_nums[@]} ... equivalent to for i in ${!fav_nums[*]} ... thank you so much!!! great pace and explanations, definitely one of the best tutorials on youtube
Thank you for another wonderful tutorial Derek. This is my second one after mySQL tutorial. We really appreciate your clear and no-nonsense way of teaching. A tutorial on AWK, GREP, SED would be helpful if you plan on doing one ever in the future.
If you are going to use vim I recommend watching a tutorial and maybe printing a cheatsheet at the beginning just until you get used to it. Also the best place to use vim is in any computer science class to show off. (People think it's hard to use. And there is a barrier to entry but once you can use it it's just the best bash text editor there is imo. Emacs is nice too. )
the two best tutorials to learn by is the bash basics tutorial by joe collins and this one after, this one teaches scripting in bash and does offer some guidance into what the commands do, but not in the same detail as joe like the chmod commands could be explained with greater depth.Good vid.
Great pace. Great structure. You got me passed all the kinks I have with the peculiar syntax the shell employs before I remembered to be pissed off looping out about it! ie, ge, le etc and ++before and after++ and calling python functions inside - these kept me from being able to read it effectively. When II tried to learn elsewhere that was the kind of stuff I never got to with their early examples that used more conventional syntax where possible but that don't look like the scripts you find in the wild and read. The good ones anyway. Thank you, sir!
Around 28:30 I think you're supposed to use '\' for lexicographic string comparison, but you used '' which are redirection operators. It's a coincidence your code worked.
Thanks for this comment, I've been trying to get this to work for about an hour you've come from the past to save my sanity. Who says time travel is dead!
Great tutorial. Derek knows art of fastest way of teaching. I had to stop a few times to learn about background material as Derek does not explain everything nor he should. It is up to you to fill in the gaps.
You know its funny, every time I think of a new concept/language/whatever i want to learn, i check your channel first. Today it was shell scripting, and low and behold look what your most recent vid is!
+Derek Banas I'm a little confused why you didn't explain that apt-get is a Linux package installer, not osx? vim (should) come already, but if not than apt-get won't work for osx.
This is exactly what I needed. I just started using elementary OS as my primary OS and with continuous updates and commands I wondered how to automate it. I come from C++ on Windows so it took me sometime. not sure I still have it correctly. I wondered why you used (( instead of (. Then [ replaced ((. But then we ran into [[ to be replaced by {. A lil confused here. Thanks for the video, Loved it.
Just want to say thanks for packing this information so tight. No one else does this because they don`t actually have that much to offer in a video so they stretch it out to 10x what it should be. I can see how it would be tempting to waste time and try to get more money with less work by filling in the videos with fluff, but I want to say thank you for not doing that!
Glad you made a shell scripting video. I tend to review your videos before I start coding, It helps me remember all the little things. This one is going to be very useful!
I am so glad that you know what you ae doing, Mr. Show off. If I want to know some thing, I'll be sure not to ask you. Like the lyrics of the song "Dirty Laundry", "After all that has been said and done, they haven't told you a thing."
Euler-Mascheroni Constant, golden ratio, base of natural log (Euler's number, sorry I'm Swiss, grew up with his face on our money...), pi and one of the Feigenbaum constants.
I must say you are really amazing at creating such short revision tutorial. They really do help to revise through everything quickly. I tried ur lisp and now this. :-)
I created a MD/PDF of your transcript and I'm happy to send it to anyone who messages :) with your permission that is! Thanks for the vid btw has helped a lot!
FWIW, I know you love to move these videos along at an aggressive pace (and even acknowledge as much in the video) but I'm not sure I would call them tutorials. Maybe they would fly as a refresher or a crash course because they might remind someone how a language or technology works if that person had learned it already. I don't see how anyone could learn from scratch with these videos because they move too fast and lack thorough explanation of key concepts. It's not a matter of slowing the video down, it's that you gloss over way too much. Fun to watch, but I know better than to start with your videos when I'm learning something new. That said, I have a lot of respect for your broad knowledge and of course your Western PA roots. Thanks for putting all this content out on RUclips--it must take a lot of work to plan, record, and edit.
Sorry you don't like them. The original concept was to provide tutorials that worked as CliffsNotes for review as well as a video that could be paused through with the provided commented code to learn from. I know they don't work for everyone. I make them this way because most every other tutorial on YT is very slow.
Great video! Shell scripting is one of the hardest skill to learn to be a good backend developer, I have been working as a software developer for many years and still can't grasp shell scripting, it's too difficult and even more difficult to work with Linux commands like awk, sed, grep.
I liked this video very much, and I can not imaging that how possible you can type and speak in such a speedy way with minimum errors, it is like you do not need to think at all, the word just came out from your mouth and fingers!!!
I just recently discovered your videos and they are great! I wonder if displaying which keys you are pressing might help, using something like screenkey. It may just add screen clutter, but might be worth evaluating. Thanks for your awesome videos!
Thank you for the input :) I looked at screenkey and I think it would be better if I just put up the keys when I issue a command. I will definitely do that from now on.
Perfect video for a student to learn. Man You deserve something. you can make an adfly account to earn more. we'll follow your links for no reason but to pay you some money indirectly.
Thank you very much :) I'll look into that. I'm actually pretty happy now. I just want to make enough to cover the books and other stuff and I make that now.
you won't believe me. i live in a world in which learning from video tutorial (or indirectly using computer) is not study. reading book is only priority for a student and parents always think one is successful only when he/she clears IIT or MBBS. these things are worthless for parents and my parents also don't support me. my only wish is to get out of here and live a real life and you are helping BIG THANKS
Thank you for taking the time to tell me :) I'm very happy that I can help. Making your parents happy is extremely important, but if your life goes as mine did around 20 or 21 you will be on your own and will have to live off of your skills. It is best to develop skills based around what you are passionate about and that can make you money. I wish you all the best
there are 12 year olds in china who can single handedly take down US govt web servers and you are still learning how to code. hope that gives you an estimate of how much catching up you need to be doing
follow the light don't try to catch up to the Chinese yet.. You'll burn out and quit.. You will start as a moron, then work up to a script kiddie, then a bottom feeder hacker, then the Russians, Indians, then Chinese 12 year olds.. Heheh. Just a thought...
Is there anything you don't know?! I have been following your work for over 4 years and I was wondering if you are a developer or teacher/professor? Thank you for your great work
Thank you for watching for so long :) I'm a private consultant that has been programming for numerous industries my whole life. I'm not a professor, but I help students with projects in my off time.
9:10 I'm a newbi in Vim (started 2 days ago yay) but a friend show me that you can simply type "yy" (double yank) to yank (copy) a whole line and then lowercase "p" to past it. Also, Ctrl+N is fking amazing
your videos are excellent. Your videos are very much useful to me, Many thanks for that. My warm regards to you.I very much congratulate you for providing cheat sheets
Jake Rieger Hey! Is the bash like it is on true Bsd and Unix and linux? Is there any support for external shell liks zsh? I develop mainly on Linux and server side soo...
That would be the best feature on Windows, for the last decades. Actually, there's many Windows ports of Bash-stuff (like Cygwin and such), but nothing beats Bash. Certainly not Powershell ...
Is anybody else bothered by the way he spells 'greater then' ? 😂 Seriously: Great tutorial! Always wanted to get better at shell scripting, thanks for the work!
Would genuinely love to know the difference between : sh example.sh ./ example bash example.sh I thought they were all the same thing but some of the stuff mentioned in the video doesn't work when using 'sh example.sh'. Thanks for the video! I enjoyed it.
bash is "born again shell" which is slow and very famous, the shebang (which is the first line looking like:) #!/bin/bash tells the script to use bash, and if you type in #!/bin/sh as the shebang, it will use whatever comes out when you type: ls -l /bin/bash if you are on debian or some other distro, you might get an arrow pointing to "dash" instead of "bash". dash is called a POSIX compliant shell which has some minimal differences in syntax and is much faster to bash. To understand the differences look at this video: ruclips.net/video/UnbmwxYi18I/видео.html If you have any questions, feel free to ask!
hey derek, I just wanted to give a suggestion. I like how you put examples sequentially and you cover most basic use cases..... Each time you clear a screen, can you take a snapshot of the terminal before the screen clears and provide those as slides? if you could pull it off without adding to your workflow too much except maybe a single alias command that clears your screen and takes snapshot just before. thanks for the great videos.
Hi I have a question and I really appreciate this video! I want to know the rule about when and how many () I should use.I'm really new to this and sorry if this is too basic.

Ok, your format and pace is outstanding. One suggestion for people like me looking for this type of content.
Expand on your "one video" trademark, experiment a little. I don't know if longer videos actually get less playtime, but it is known that RUclips's content gets shorter and shorter as people's attention spans are changing. Don't conform to this. Capitalize on the "in one video" thing and maybe add a unique hotword to them (fastpace synonym - something catchy). Man this video style is just great for me, you got a new sub and I'm sending your channel to everyone who wants to learn fast. I rarely comment on videos but had to let you know this is special here. Just gotta promote the brand if your other videos are similar.

I don't see how anyone could learn from scratch with these videos because they move too fast and lack thorough explanation of key concepts. It's not a matter of slowing the video down, it's that you gloss over way too much. Fun to watch, but I know better than to start with your videos when I'm learning something new. That said, I have a lot of respect for your broad knowledge and of course your Western PA roots. Thanks for putting all this content out on RUclips--it must take a lot of work to plan, record, and edit.
Sorry you don't like them. The original concept was to provide tutorials that worked as CliffsNotes for review as well as a video that could be paused through with the provided commented code to learn from. I know they don't work for everyone. I make them this way because most every other tutorial on YT is very slow.
I feel like having unlimited power after watching this video, Thanks Derek!
Programming is Awesome! It is the first step to gaining super powers :)
Very useful tutorial and most of the basics have been covered. Really appreciate it !!!
Great video! Shell scripting is one of the hardest skill to learn to be a good backend developer, I have been working as a software developer for many years and still can't grasp shell scripting, it's too difficult and even more difficult to work with Linux commands like awk, sed, grep.
Thank you :) I'm happy the video helped
Just simply Woooow...first thing i did after watching this vid is subs...ur vid brought lotta confidence in me..thanks for the awesome work...
Thank you for the nice compliment :)
I liked this video very much, and I can not imaging that how possible you can type and speak in such a speedy way with minimum errors, it is like you do not need to think at all, the word just came out from your mouth and fingers!!!
Thank you very much :) I'm nothing special I have just had a lot of practice. I've made almost 800 videos.
you were a developer before?
I still work as a programmer
In order to close the overall if statement you're going to type fi. Because it's if backwards.
Cool.
Now we just need to change HTML closing tags to LMTH
Awesome !!. I like the way you explained all in a single video .
Thank you :) I'm glad it helped
better than bought tutorials, thanks Derek
This is awesome, you channel is the only serious one that i subscribed
Thank goodness I took that Java class!............. Bash scripting on steroids. Thanks, Man
I'm very happy I could help :)
Thank you for this. I took a whole lot of notes from this video (in the form of shell scripts)
I'm happy you liked it :)
You need to talk more about the "all in the shell are just strings" a little bit more.
You could do a 3 hour video on just learning VIM, Derek, lol.
Yes I could. I love Vim :)
well you should. one of your "learn in one video" series episodes.
This is AWESOME!
We need more videos like this.
I just recently discovered your videos and they are great! I wonder if displaying which keys you are pressing might help, using something like screenkey. It may just add screen clutter, but might be worth evaluating. Thanks for your awesome videos!
Thank you for the input :) I looked at screenkey and I think it would be better if I just put up the keys when I issue a command. I will definitely do that from now on.
Oh cool! Yeah that makes sense. Thanks very much for considering trying that. :-)
No problem. I love getting input on how to improve the videos
8:15 - I believe you can also declare a constant with "readonly" (same effect as "declare -r").
Perfect video for a student to learn. Man You deserve something. you can make an adfly account to earn more. we'll follow your links for no reason but to pay you some money indirectly.
Thank you very much :) I'll look into that. I'm actually pretty happy now. I just want to make enough to cover the books and other stuff and I make that now.
you won't believe me. i live in a world in which learning from video tutorial (or indirectly using computer) is not study. reading book is only priority for a student and parents always think one is successful only when he/she clears IIT or MBBS. these things are worthless for parents and my parents also don't support me. my only wish is to get out of here and live a real life and you are helping BIG THANKS
Thank you for taking the time to tell me :) I'm very happy that I can help. Making your parents happy is extremely important, but if your life goes as mine did around 20 or 21 you will be on your own and will have to live off of your skills. It is best to develop skills based around what you are passionate about and that can make you money. I wish you all the best
Thanks. You're a good person. thanks for the advice. have a nice day my friend
I'm very happy that I can help :)
Easy to follow and absorb the scripting content presented - Thank You!
Thank you very much :)
Very informative. Thanks for putting in so much effort to make such videos
Disclaimer: Best used with .75x speed
i've understand all my semester in that hour thank u very much ps; like ur voice *.*
Thank you :) I'm very happy that it helped
man, how old are you and how old did you start learning to code?..I'm impressed with the amount of languages and techniques and tools you know
Thank you :) I'm 42 and I started programming when I was 10. I'm not that smart. Anyone can do this
I started coding with 18 and now I'm 22, really thank you for the reply, now I see I'm at the right pace knowing just a few languages :)
there are 12 year olds in china who can single handedly take down US govt web servers and you are still learning how to code. hope that gives you an estimate of how much catching up you need to be doing
follow the light don't try to catch up to the Chinese yet.. You'll burn out and quit.. You will start as a moron, then work up to a script kiddie, then a bottom feeder hacker, then the Russians, Indians, then Chinese 12 year olds.. Heheh. Just a thought...
I lol'd =))))
But seriously man, don't compare yourself with that 12 years old kid.
Thanks for listening to your fans, an informative video Derek
Thank you :) Yes if enough people ask me for something I do my best to deliver
Is there anything you don't know?! I have been following your work for over 4 years and I was wondering if you are a developer or teacher/professor? Thank you for your great work
Thank you for watching for so long :) I'm a private consultant that has been programming for numerous industries my whole life. I'm not a professor, but I help students with projects in my off time.
Good to know :)
Awesome Video..
Makes kickstarting shell scripting a lot easier.
Thanks Derek
Thank you :) I'm glad it helped
9:10 I'm a newbi in Vim (started 2 days ago yay) but a friend show me that you can simply type "yy" (double yank) to yank (copy) a whole line and then lowercase "p" to past it. Also, Ctrl+N is fking amazing
Thank you for sharing :)
your videos are excellent. Your videos are very much useful to me, Many thanks for that. My warm regards to you.I very much congratulate you for providing cheat sheets
Great work. In near future can we see "Powershell in one video?"
Thank you :) I'll see what I can do
Bash is coming to windows... why need powershell?
Bash is already on windows if you're part of the insider program. It's awesome.
Jake Rieger Hey! Is the bash like it is on true Bsd and Unix and linux? Is there any support for external shell liks zsh? I develop mainly on Linux and server side soo...
That would be the best feature on Windows, for the last decades. Actually, there's many Windows ports of Bash-stuff (like Cygwin and such), but nothing beats Bash. Certainly not Powershell ...
Is anybody else bothered by the way he spells 'greater then' ? 😂 Seriously: Great tutorial! Always wanted to get better at shell scripting, thanks for the work!
I am bothered by erb herb and sodder solder only...I know he didn't say either but I just have to tell someone
Straight to the point just how I like it
Happy I could help :)
This video is really helpful, thanks for making it. Covered all the things in 1 video!!
Thank you :) I'm glad it helped
You are a life saver Derek.
Thank you :) I'm happy I can be of help
Ah yes, a vim tutorial, just what I wanted to see when opening a video on shell scripting.
Nice name
Hi Derek I love the way you cover any language in one hour session. This is the best tutorial on shell script available so for. Thank you :)
Thank you for the nice compliment :)
Would genuinely love to know the difference between :
sh example.sh
./ example
bash example.sh
I thought they were all the same thing but some of the stuff mentioned in the video doesn't work when using 'sh example.sh'.
Thanks for the video! I enjoyed it.
bash is "born again shell" which is slow and very famous, the shebang (which is the first line looking like:)
#!/bin/bash
tells the script to use bash, and if you type in
#!/bin/sh
as the shebang, it will use whatever comes out when you type:
ls -l /bin/bash
if you are on debian or some other distro, you might get an arrow pointing to "dash" instead of "bash". dash is called a POSIX compliant shell which has some minimal differences in syntax and is much faster to bash.
To understand the differences look at this video:
ruclips.net/video/UnbmwxYi18I/видео.html
If you have any questions, feel free to ask!
I've been braindead for so long, I can't even follow your great tutorial
hey derek, I just wanted to give a suggestion. I like how you put examples sequentially and you cover most basic use cases..... Each time you clear a screen, can you take a snapshot of the terminal before the screen clears and provide those as slides? if you could pull it off without adding to your workflow too much except maybe a single alias command that clears your screen and takes snapshot just before. thanks for the great videos.
Thanks for the suggestion. I'll see if I can implement something similar in the future :)
Perfect timing for this awesome video! Thanks Derek!
You're very welcome :)
23:25 It's easy to mix up 'then' and 'than'. Those echoes should use the latter
When you said "sh-bang" I immediately thought you were referring to Ricky Martin's song. Then I realized I'll get flack for knowing Ricky Martin.
+Fruit F*cker I say all sorts of weird things and I totally remember Ricky Martin 😄
hahaha vim, I'm an emacs evil mode man. best of both worlds.
Great tutorial btw. Bash is a very important tool for any programmer.
Thank you :) For some strange reason I've stuck with Vim?
very well covered in one hour.
Thank you very much :)
Nice video and really helpful. You dont waste time, thank you
Thank you :)
Hi I have a question and I really appreciate this video! I want to know the rule about when and how many () I should use.I'm really new to this and sorry if this is too basic.
Thank you :) I'm not sure what you mean by the question. Can you give me an example of what confuses you?
You Blink, You Miss! I loved it, it was fun... :D Great Work.
Thank you very much :)
Great video!
Just so you know, at 53:24 you forget to put the "!" before "fav_nums" (i.e. ${!fav_nums[@]}) in order to print the indices.
Sorry about the typo
