Ruby – How to search a folder and all of its subfolders for files of a certain type

This should solve your problem:

import static groovy.io.FileType.FILES

new File('.').eachFileRecurse(FILES) {
    if(it.name.endsWith('.groovy')) {
        println it
    }
}

eachFileRecurse takes an enum FileType that specifies that you are only interested in files. The rest of the problem is easily solved by filtering on the name of the file. Might be worth mentioning that eachFileRecurse normally recurses over both files and folders while eachDirRecurse only finds folders.

Try this one:

#!/bin/bash
find $1 -type f -exec stat --format '%Y :%y %n' "{}" \; | sort -nr | cut -d: -f2- | head

Execute it with the path to the directory where it should start scanning recursively (it supports filenames with spaces).

If there are lots of files it may take a while before it returns anything. Performance can be improved if we use xargs instead:

#!/bin/bash
find $1 -type f -print0 | xargs -0 stat --format '%Y :%y %n' | sort -nr | cut -d: -f2- | head

which is a bit faster.
