fusecompress_offline (1) Linux Manual Page

NAME

fusecompress_offline – decompress or compress data without need to mount the compressed virtual filesystem

SYNOPSIS

fusecompress_offline [-h] [-v] [-o OPTIONS] path

DESCRIPTION

If compression method is set the data will be compressed by required compression method. Files already compressed by a different compression method are recompressed to the required compression method. Files already compressed by the required compression method are left untouched. If compression method is not set (using -o fc_c) then file(s) are decompressed.

Path may be directory or file. Directories are processed recursively.

This allows you to, among other things, "compress" an existing folder (ex:) $ fusecompress_offline -o fc_c:lzma formerly_uncompressed_folder

and to "decompress" an existing compressed folder (ex:)

$ fusecompress_offline compressed_folder

OPTIONS

-h, –help

Prints help.

-v, –version

Prints version.

-o, –options

fc_c:arg set compression method (lzo/bzip2/zlib/lzma) (default:zlib)

fc_b:arg set size of the blocks in kilobytes (default:100)

fc_d run in debug mode

fc_ma:arg1;arg2 files with passed mime types to be always not compressed

fc_mr:arg1;arg2 files with passed mime types to be always compressed

Lzo is the fastest, bzip2 has high compression ratio, but it is the slowest, zlib is somewhere between them in terms of speed and compression ratio and lzma has highest compression ratio, it’s compression speed is better than bzip2 and decompression is fast.

Block size influences compression ratio. Bigger block size allows better compression ratio, but random access to data will be slower and memory requirements will be bigger.
