At 1:12:00 the script checks for the string that appears first in the dictionary order , not the lengths of the strings At 1:15:11 , str1^ capitalizes the first letter of the string, str1^^ capitalizes the whole string, str^^h capitalizes every occurrence of h in the string, but instead of str^^ , in the video str^ was used

I've been through quite a few online Bash courses, but this was by far the best. Really superb. He explains everything slowly and painstakingly, not glossing over anything, and leaving nothing to chance. Even complicated concepts are made clear.

[@vladislavvolokhov4208]

1:15:10 Actually, to change the string cases, here are the right options: 1) To upper case: str=${str^^} this is a string -------> THIS IS A STRING 2) To lower case: str=${str,,} THIS IS A STRING -------> this is a string 3) To start with a capital letter: str=${str^} this is a string -------> This is a string ^does not change the case to lower, two commas do Hope this helps someone.

I really really love what you've done here thank you very much for taking the time to run through all of this for us. I think what would drive the point home even more is to provide some real-world examples and how you would apply each of the scripts. Your examples are fabulous, but they're abstract

I am search bash script course in Russian KZbin, but i find this lesson, it is really awesome work, ty so much i hope you have inspiration for new video

[@hazalberilcatalak4477]

I appreciate the effort put into this video lecture and I'd like to share my personal points for improvement. It's an okay intro in my humble opinion, and some important stuff is either lacking or overlooked. 1. In string processing, string comparisons are made by checking the ASCII code of each character, thus "abc" is not equal to "acb". In the lecture, it was represented like the length of the strings are checked. Maybe in the earlier versions, it could be true (by looking at the date of the video uploaded), but in the latest version, it is not. I didn't come across such a comparison in Java, Matlab, or Python, and it bugged me. 2. If you'll upload a newer version of this lecture, I would suggest, please, indicate the type of variable you're using. E.g, when you're showing how to write and if conditional for the first time, indicate that the program understands the variables when you use double quotes and dollar sign, and whether or not it is a string. 3. No need to mention that you've cut the part where you've explained case statement, so maybe you may want to explore that part in the newer version of the video. If there'll be no newer video on this topic, maybe you'll update the website accordingly. Thank you for the effort.

[@Andy-xv4dj]

Can agree 100% with that. He sometimes gives wrong ideas about what's happening behind the scenes. As you've mentioned with string comparison but also with export. In this chapter he should have at least mentioned local and global/environment variables. He just says that we are sending it to the other script which can be confusing. Haven't watched further yet. Not sure if he wants to over simplify stuff or if he really doesn't know better. Besides this I'm happy that somebody puts so much effort into and provides an 3h video on shell scripting.

Thanks buddy! Yesterday in 4 days I completed this tutorial. I am not from the programming field.

[@bobhutchins557]

Great video! Just a comment on converting a string to lowercase. At 1:14:00 (close to it), you mention using ${st1^} to convert the string st1 to lowercase. However, ${st1^} converts st1 to proper noun form (i.e., the first letter of the string is uppercase; remaining letters are lowercase). I believe the proper way to convert st1 to lowercase is ${st1,,}.

[@bradybrandt8220]

The string comparison operators are not comparing lengths they are comparing ascii values. You can test this by entering "A" for the first string and "a" for the second string. You will see that "A" is smaller because it has an ascii value of 65 and "a" is larger because it has an ascii value of 97.

[@velmurugansubramaniam8051]

[@il4w]

The video is really thorough great content! unset doesn't modify the respective indexes of remainder of array though (array after the removed element) as you would expect with a standard remove operation. So, instead doing this is better:- active_employees=("${active_employees[@]:0:2}" "${active_employees[@]:3:1}") where 2 is the index you might wanna remove 😁
