I'll first state the situation. There are N JPG - format pictures in my computer, and the names of the pictures are all jumbled. Is there a way to rename these pictures starting from 1 and renaming them in sequence? For example: 1.jpg, 2.jpg, 3.jpg. I've tried many methods but still can't make it work. I think I should use the FOR /L command, but no matter how I change it, I can only rename one file. I'm really depressed. Please, all you experts, give me some advice.

Finally, please trouble all the experts to explain the detailed code. Thanks again.

There have been many such problems, exactly the same as yours.
http://www.cn-dos.net/forum/viewthread.php?tid=37611&fpage=1&highlight=%E6%89%B9%E9%87%8F%E4%BF%AE%E6%94%B9%E6%96%87%E4%BB%B6%E5%90%8D

for %%a in (*.jpg) do (
set/a n+=1
call ren "%%a" %%n%%.jpg
)

Short, super short... Speechless... Helpless... Envious...

The code above is already concise to the point where there's not much to explain. If there is, it's the call part... This is a very good example. The poster should master the skills! (Depressed... I don't know this... The poster is really lucky, just came and has something to learn)

Paste one of mine, which is very inefficient. It was written when I just started: (Without using the set command)
ren *.jpg *.
for /l %%a in (1,1,10000) do (
ren *. a-%%a.jpg 2>nul
if not exist *. exit
)
Explanation: Rename all jpg files to format
Then the for /l %%a from 1 to 10000
f1 -- Rename *. to 1.jpg Because of the system error, so only one 1.jpg can be renamed
f2 -- Rename *. to 2.jpg Because it's ren *. so the previous 1.jpg won't be changed to 2.jpg
And still extract one 2.jpg from the remaining to achieve the effect of renaming one by one.
f3 f4 and so on
This method is not supported for everyone to use. It's purely going the long way... Having nothing better to do, obviously there's a精华 post, but still insist on writing one of my own.

Hehe```Thanks```Actually I think going the long way is the shortcut to becoming an expert ah`

But why aren't the numbers arranged in order when using the code from floor 2? To be precise, the numbers start to be arranged correctly only after reaching 100. The numbers before 100 are all renamed in a jumping manner

It's not about renaming by jumping, but the different arrangement order. You right - click and arrange the names. It runs normally on my computer.

I saw a batch - modified one before, which first deleted to the recycle bin, and thought it was quite troublesome. It turns out there is such a simple one here. Learned it..

I have sorted it, but it's still as I said. So I created 2 batches. After executing one, the arrangement is abnormal, and then executing the second one is fine. What's the problem in between? Is it related to delay?

Maybe...

Try changing for %%a in (*.jpg) do (
to　　for /f "tokens=*" %%a in ('dir *.jpg') do (

I think it's possible that after renaming, the files that have already been renamed are still being read by for, causing the same part of the files to be renamed repeatedly

But when I tested here, there was no problem

I've learned a lot from the post on the 2nd floor, and I'll also bump up the old thread
