Bash Question

How do I find all files that do not begin with a given prefix in bash?

I have a bunch of files in a folder:


I want to find all the files that do not start with a given prefix and save the list to a text file. Here is an example for the files that do have a given prefix:

find bar_* > Positives.txt

This should do the trick in any shell

ls | grep -v '^prefix'

The -v option inverts grep's search logic, making it filter out all matches. Using grep instead of find you can use powerful regular expressions instead of the limited glob patterns.
