jdupes is a command-line tool for identifying and optionally deleting duplicate files. Unlike simple checksum-based duplicate finders, jdupes performs thorough comparisons, including byte-by-byte verification, to ensure true duplication. This minimizes the risk of false positives. It's particularly useful for cleaning up disk space occupied by redundant files, especially in large file systems like media collections or backups.

jdupes offers a flexible set of options for controlling its behavior, including recursive directory traversal, ignoring hidden files, displaying detailed output, and securely deleting duplicate files. The user must confirm the deletion to prevent accidental loss of important files.

jdupes is designed to be safe and efficient, but users should always exercise caution when deleting files, especially when using automated deletion options. It's recommended to test jdupes on a small subset of files before running it on an entire file system.

Always double-check the files selected for deletion before confirming, especially when using non-interactive deletion. Backups are strongly recommended before using any file deletion tool.

jdupes returns 0 on success and a non-zero value on error.

jdupes is a fork of fdupes. It was created to improve upon some perceived shortcomings of fdupes. jdupes continues to be actively maintained.
