I have I bunch of files in a directory, named like this:

cat.10171.jpg cat.12421.jpg cat.3421.jpg

I want to move part of them to another directory using this from Colab notebook:

!mv cat.{0..499}.jpg /content/train
I have an error:

mv: cannot stat 'cat.{0..499}.jpg': No such file or directory
Any ideas how to do this and what is the reason?

Stack Overflow is a site for programming and development questions. This question appears to be off-topic because it is not about programming or development. See What topics can I ask about here in the Help Center. Perhaps Super User or Unix & Linux Stack Exchange would be a better place to ask. – jww Jun 30 '18 at 0:31

This also worked for me:

shutil.move("path/to/current/file", "path/to/new/destination/for/file")
So:

shutil.move("/content/cat.10171.jpg", "/content/train")

!mv "/content/P14-Convolutional-Neural-Networks.zip" "/content/drive/My Drive/U/señales/colab/"
you have to use "" to make it readable

I have an idea , you don't need to move them to colab because after some hours , Colab will restart automatic and all data will removed , so what's solution for that ? Simply, you can copy them to colab from Drive but How can i do that ? Here's solution for that :

!cp "/content/drive/My Drive/*.jpg" "/content/train"
BUt if you still want to move them not copy , Here's solution for that :

!mv "/content/drive/My Drive/*.jpg" "/content/train"
Conclusion , " cp " for copy and " mv " for move
