Excluding filenames from the find output

There are times when you do not need to display everything from the output of find(1). So, in this subsection, you will learn a technique that allows you to manually exclude files from the output of improvedFind.go based on their filenames.

Note that this version of the program will not support regular expressions and will only exclude filenames that are an exact match.

So, the improved version of improvedFind.go will be named excludeFind.go. The output of the diff(1) utility can reveal the code differences between improvedFind.go and excludeFind.go:

$ diff excludeFind.go improvedFind.go
10,19d9
< func excludeNames(name string, exclude string) bool {`
<     if exclude == "" {
<           return false
<     }
< if filepath.Base(name) ...
