Batch Tutorial 10 - FOR Loops

[shadetreesam]

Excellent tutorial! Here's why:

This is the right way to introduce the for-next control structure, because all the remaining forms of for-next, including those that involve folder and file processing, are derived from these two primitive forms. Because the for-next loop is often used for folder and file processing, many beginners jump right into the folder and file processing forms of for-next, which I believe is a mistake, because the abstractions used to select the folders and files being processed often obscure the underlying behavior of the for-next loop. When viewing the combined effect, it isn't always clear exactly what is being done by the folder and file operations encapsulated within the abstract expressions, and what is being done by the for-next processing.

If you first learn how the for-next control structure works (as described in this video), and then add on the abstractions used in folder and file processing, you will have a much better understanding of how the for-next loops that process folders and files actually work, and will know how to properly code the for-next loop to perform folder and file operations and obtain the results you want.

My only suggestion is to the author is add some of the coding examples shown in the video to the comments section.

Thanks for the tutorial although I think you talked way too fast. I am trying to look at a directory and run every file with a specific extension. I am not sure how to do that

I only knew how to do this in Java before I watched this, and gave up on making a C# utility because it was taking me too long. This is the perfect bodge-it-together solution for making a number of folders necessary for files, and I'd bet I can make it work with renaming files as necessary too

Your explanation is very well sorted out. A lot of tutors on the web just don't explain half of the functions which leaves me guessing about the workings of this command. Thanks

for /f "tokens=1* delims=0123456789" %%a in ("A0%VAR:"=%") do (
if not "%%b"=="" goto :invalid
)

someone can explain me what this does? specifically the part ("A0%VAR:"=%") I can't get it

what does A0% means?

if i have a text file that contains Hello World!
can i display it like this? World! Hello
and also is it possible to save it into another text file?

[lucaslindgren]

I recommend using Sublime Text for scripting in Batch. It's much better!

Hey, great tutorial, what version of notepad are you using, i am not getting those color highlighting for functions and braces

[ingamelevi]

Wait this is from all the way back in 2011? I was 11 when this tutorial was uploaded.

Is there any reason you use single ' ' instead of " "?

[kirankulkarni]

This is great. I wanted to know how to read 2nd row and 2nd column of a csv file

[thimitha]

thanks now i can make a file that rickrolls people 69 times

[krutarthraut]

dill-li-meter, lol, great video thanks for the help!

[sivakrishnadindi]

Thank you. I got a solution. Good tutorial

Can anybody help me fo the code? 🙏

Write a program in batch file using conditional statement that let the user plays a simple jack n poy game.

The instruction of this code: there are 2 players (player 1 and player 2). The turn starts at player 1 then player 2. The allowed inputs of both players are:
P – - Paper
R – - Rock
S - Scissor
if the user tries to input other character aside from the 3. Create a goto function that allows the user to input again.
