compsize

Calculate the compression ratio of a set of files on a btrfs filesystem. See also: btrfs filesystem for recompressing a file by defragmenting it. More information: https://manned.org/compsize.

• Calculate the current compression ratio for a file or directory:

sudo compsize {{path/to/file_or_directory}}

• Don’t traverse filesystem boundaries:

sudo compsize {{[-x|--one-file-system]}} {{path/to/file_or_directory}}

• Show raw byte counts instead of human-readable sizes:

sudo compsize {{[-b|--bytes]}} {{path/to/file_or_directory}}
