FILE : a filename
with no FILE, or when FILE is - , read standard input
Arguments :
- -# : # compression level (1-19, default:3)
+ -# : # compression level (1-19, default: 3)
-d : decompression
-D file: use `file` as Dictionary
-o file: result stored into `file` (only if 1 input file)
--ultra : enable levels beyond 19, up to 22 (requires more memory)
--long : enable long distance matching (requires more memory)
--no-dictID : don't write dictID into header (dictionary compression)
---[no-]check : integrity check (default:enabled)
+--[no-]check : integrity check (default: enabled)
-r : operate recursively on directories
--format=gzip : compress files to the .gz format
--format=xz : compress files to the .xz format
--format=lzma : compress files to the .lzma format
--test : test compressed file integrity
---[no-]sparse : sparse mode (default:disabled)
+--[no-]sparse : sparse mode (default: disabled)
-M# : Set a memory usage limit for decompression
-- : All arguments after "--" are treated as files
--train-cover[=k=#,d=#,steps=#] : use the cover algorithm with optional args
--train-legacy[=s=#] : use the legacy algorithm with selectivity (default: 9)
-o file : `file` is dictionary name (default: dictionary)
---maxdict=# : limit dictionary to specified size (default : 112640)
+--maxdict=# : limit dictionary to specified size (default: 112640)
--dictID=# : force dictionary ID to specified value (default: random)
Benchmark arguments :
- -b# : benchmark file(s), using # compression level (default : 1)
+ -b# : benchmark file(s), using # compression level (default: 3)
-e# : test all compression levels from -bX to # (default: 1)
- -i# : minimum evaluation time in seconds (default : 3s)
+ -i# : minimum evaluation time in seconds (default: 3s)
-B# : cut file into independent blocks of size # (default: no block)
--priority=rt : set process priority to real-time

to make files with many zeroes smaller on disk.
Creating sparse files may save disk space and speed up decompression by
reducing the amount of disk I/O.
- default : enabled when output is into a file,
+ default: enabled when output is into a file,
and disabled when output is stdout.
This setting overrides default and can force sparse mode over stdout.
* `--rm`:
suppress warnings, interactivity, and notifications.
specify twice to suppress errors too.
* `-C`, `--[no-]check`:
- add integrity check computed from uncompressed data (default : enabled)
+ add integrity check computed from uncompressed data (default: enabled)
* `--`:
All arguments after `--` are treated as files
* `-e#`:
benchmark file(s) using multiple compression levels, from `-b#` to `-e#` (inclusive)
* `-i#`:
- minimum evaluation time, in seconds (default : 3s), benchmark mode only
+ minimum evaluation time, in seconds (default: 3s), benchmark mode only
* `-B#`, `--block-size=#`:
cut file(s) into independent blocks of size # (default: no block)
