files starting with u number does not accept valid solution

[codesinthedark]

basename -a $(find . -type f) | grep ^[0-9] is not accepted as a solution but it outputs the same lines as accepted solution: ls -R|grep ^[0-9]|grep -v dir

Only difference that the lines are in different order and in the exercise it is not specified that we need a specific order. For example ls -U would not work because it traverses the files in directory order.

Also the accepted solution should not be accepted because if directories do not contain "dir" it would not work while basename -a $(find . -type f) | grep ^[0-9] would work.

Edit: not an issue

It breaks on files with spaces so the failure is expected here:

bash(0)> basename -a $(find . -type f)

You are correct. If I try find . -type f | while read fname; do basename "$fname" | grep ^[0-9]; done then it works :) Thank you 👍
