Over the years, any Linux user will tend to collect multiple copies of files in their system. This could be from from unpacking distributions in different areas, copying files for safekeeping, or any number of other reasons. In this training video Arnold Robbins shows you how to clean up your system. He will walk you through a file tree to identify duplicate files by:
Using the find command to walk a directory tree.
Actioning the results with xargs.
Sorting, and then printing the duplicate files found.
All of this is accomplished using a simple 20-line shell script; and is explained in a way that any level of Linux user can understand and replicate.
