Advanced Bash Scripting Tutorial

This video is not being monetized, and no ads (advertising) should be shown.

Bash, or the Bourne Again Shell, is a widely popular command-line interpreter for administration and programming tasks. It's also the default option on Mac OS X and Linux. But Bash is different than most scripting languages. This course spends some time running you through the syntax—introducing variables, numbers, and control structures—so you can start writing scripts right away. Shows you how to wrap up multiline operations in one file, implement flow control, and interact with users to get input. Plus, offers challenges along the way that allow you to put what you've learned to the test.

Made this for self reference. Figured I'd share in case someone wants to know what you will see in this video.

Rare opportunity that someone really knows what he's talking about, instead of usual

Great ! This will help me creating my scripts even more complex and easy for others.

Here's a tip since this guy is so fast. Change the playback speed to 1.5 so you can keep up.

If you want real-time, 0.75x playback

"This video is not being monetized" is that because you directly lifted this video off of someone's course?

the upper limit of files you mentioned on mac looks awfully similar to the default ulimit setting for open files ive seen on linux distros. Might be worth checking if Mac uses ulimit and whether it can be extended.

Hi. Is shell language a good start point to learn programming/coding? I know it’s a very weird and limited language but is it still a good option to start with? Thanks.
