I'm a newbie, and I don't understand this sentence. I saw it when learning the for command.

Also, can someone give a tutorial on the for command? What I found online is either just copying the help of for or written incorrectly. I copied the example it gave and it didn't run, and even copied it and it didn't run. Ugh. Thanks, thanks.

Look at here:

Maybe you will have a new understanding of the FOR command ........

Thanks

But I still can't run its example, please help see what's wrong: (I copied it up.)

klot\>for %a in (c: d: e: f do @dir %a\ 　 find "bytes free"
More?
More?
More?

klot\>for %a in (c: d: e: f do @dir %a\ find "bytes free"
More?

klot\>for %a in (c: d: e: f do @dir %a\ find "bytes free" )
The syntax of the command is incorrect.

I advise you to study his grammar, don't be eager to execute and debug his commands. Try executing this: for %a in (c: d: e:) do @dir %a\|find "available bytes"
Before the following statement is effective, you need to execute CHCP 437 and then execute the following code, because he uses "bytes free" as the search condition: for %a in (c: d: e:) do @dir %a\|find "bytes free"

“bytes free” is the screen display in English state, and it is impossible to appear in the CMD in your Chinese state.

Thanks for the guidance.
I didn't want to run the code at first either, but if I didn't run it, I couldn't see the effect, and I didn't really believe if the code in the tutorial would work. Like me, who is so noob, I probably can't spot wrong code, so I had to run it. Isn't practice the best way to understand things, heh.

Finally, thanks to both of you for the help.

This is the result after I ran it, and it worked:)
klot\>for %a in (c: d: e:) do @dir %a\|find "bytes free"
4 Dir(s) 1,807,380,480 bytes free
8 Dir(s) 2,930,888,704 bytes free
10 Dir(s) 3,651,493,888 bytes free

Practice is the best way to understand things

Hehe, that's what it is said, but the condition is when you have a general understanding
