dupPro

dupPro is a command-line utility designed to identify and report duplicate files within specified directories. It operates by calculating cryptographic hashes for each file and then comparing these hashes to detect identical content, regardless of filename or location. The tool offers various options for customizing the search, including the ability to exclude certain directories or file types, and to specify the depth of the search.

The primary function of dupPro is to help users manage disk space by locating redundant files. It can be configured to display a list of duplicate files, along with their paths, or to perform actions such as deleting the duplicates, leaving a user-defined number of copies. The output can be formatted in different ways, making it suitable for direct use in scripts or for manual review.

dupPro is typically used by system administrators and power users for tasks such as cleaning up large datasets, managing software installations, or ensuring data integrity. Its efficiency comes from its hash-based comparison, which avoids the need for byte-by-byte comparisons of entire files. The tool is known for its speed and relatively low resource consumption, making it a practical choice for scanning large storage volumes.
