Check These Out

highlight with grep and still output file contents

Diff two directories by finding and comparing the md5 checksums of their contents.
Compute the md5 checksums for the contents of two mirrored directories, then sort and diff the results. If everything matches, nothing is returned. Otherwise, any checksums which do not match, or which exist in one tree but not the other, are returned. As you might imagine, the output is useful only if no errors are found, because only the checksums, not filenames, are returned. I hope to address this, or that someone else will!

A function to find the newest file in a directory
Works recusivley in the specified dir or '.' if none given. Repeatedly calls 'find' to find a newer file, when no newer files exist you have the newest. In this case 'newest' means most recently modified. To find the most recently created change -newer to -cnewer.
