I'm trying to find multiple files with 40 hexadecimal digits. I can use
ls -l | grep '[0-9A-F]\{40\}'
And see the files I want to see them but I want to use find for this for the sake of the challenge. I tried:
find . -regextype grep -regex '[0-9A-F]\{40\}'
It doesn't work. I would be happy to understand this matter.
Bonus question: How this can be done with shell regular expressions like this: ls -l [0-9A-F]{40}?
