"i prefer to move these along quickly and let you adjust yourself to a pace youre comfortable with" THANKYOU.

[wesg]

The best tech vids I have found! I REALLY like the fast pace, and no unnecessary-fluff approach you take. Keep up the great work!

[jamespretlow]

I like the speed of your tutorial. There is no time to get distracted.

[SuperDanny]

Derek you're a mind reader I just started my internship and it's all bash scripting... Great timing Thanks!

[christopherfujino]

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!

[ravikiranmandha]

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.

[ilshatabdulmanov]

Out of many, best in its kind.
This tutorial beats a line of many others I`ve watched so far.
This guy deserves a thumbs up.

[mikeseitz]

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!

[qodino]

This was the best Shell Scripting tutorial I’ve seen on Youtube so far. Very well done. Thanks for sharing!

[kaiergin]

Found out I needed to learn shell scripting today, Derek uploaded yesterday. Perfect timing and great video. Thanks so much!

[samsungyou]

Again.. This is the Best.. The BEST.. The best tutorial ever.

Thanks a lot Derek . It really helped a lot....

[tainoroyal]

Great tutorial. I love the pace of these. There's no waffle just pure gold.

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

Very useful tutorial and most of the basics have been covered. Really appreciate it !!!

[Earlosaur]

The amount of material you produce is just... words can't describe how much I love you.

[lapinblanc]

Great videos, Derek
100 miles per hour, but short enough to watch in one sitting. Best tutorials on YouTube :)

[sebastiantu]

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!

[sedeanimugamez]

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.
