Removing files matching a numeric range regular expression
You can try
rm some-files-with-numbers{0..300}
This will delete:
some-files-with-numbers0
some-files-with-numbers1
some-files-with-numbers2
...
some-files-with-numbers300
I like superuser’s answer, but to add another possibility:
find . -regex './some-files-with-numbers[123]?[0-9]?[0-9]' -delete
