[--shared-size SHARED_SIZE] [--tolerance TOLERANCE]
[--dedupe] [--repetitions REPETITIONS] [--flush]
[--speed SPEED]
root [root ...]
positional arguments:
root Files / directories that need defragment
optional arguments:
-h, --help show this help message and exit
--verbose, -v
--dry-run, -n
--target-size EXTENT_SIZE
Target extent size (default: 128MB)
--acceptable-size SMALL_EXTENT_SIZE
Acceptable extent size (default: 32MB)
--large-extent-size LARGE_EXTENT_SIZE
Ignorable extent size (default: 64MB)
--shared-size SHARED_SIZE
Ignorable shared extent size (default: 1MB)
--tolerance TOLERANCE
tolerable fraction in both size and number of extents
(default: 0.1)
--dedupe use ioctl FIDEDUPERANGE to defrag hopefully

defragment multiple times (default: 1)
--flush
--speed SPEED Disk IO speed that estimate pause between files
(default: 0, no pause)
btrfslime.dedupe performs a specialized deduplication of files with equal size.
The equal-size assumption avoids hashing unnecessary files and occupying large space for file hashes.
This tool should be helpful for media file deduplication.
usage: btrfslime.dedupe [-h] [--verbose] [--db-file DB_FILE] [--skip-scan]
[--skip-hash] [--skip-dedupe] [--reset-done]
[--reset-hash] [--no-purge-missing]
roots [roots ...]
positional arguments:
roots Files / directories that need dedupe
optional arguments:
-h, --help show this help message and exit
--verbose, -v
--db-file DB_FILE Cache database file for file hashes (default: dedupe.db)
--skip-scan Skip file scanning phase
--skip-hash Skip file hashing phase
--skip-dedupe Skip dedupe phase
--reset-done Reset the done flag
--reset-hash Reset the computed hash values
--no-purge-missing Do not purge missing entries from the database
