NAME¶
minilzip - reduces the size of files
SYNOPSIS¶
minilzip [
options] [
files]
DESCRIPTION¶
Minilzip - Test program for the lzlib library.
OPTIONS¶
- -h, --help
- display this help and exit
- -V, --version
- output version information and exit
- -b, --member-size=<bytes>
- set member size limit in bytes
- -c, --stdout
- send output to standard output
- -d, --decompress
- decompress
- -f, --force
- overwrite existing output files
- -F, --recompress
- force recompression of compressed files
- -k, --keep
- keep (don't delete) input files
- -m, --match-length=<bytes>
- set match length limit in bytes [36]
- -o, --output=<file>
- if reading stdin, place the output into <file>
- -q, --quiet
- suppress all messages
- -s, --dictionary-size=<bytes>
- set dictionary size limit in bytes [8 MiB]
- -S, --volume-size=<bytes>
- set volume size limit in bytes
- -t, --test
- test compressed file integrity
- -v, --verbose
- be verbose (a 2nd -v gives more)
- -1 .. -9
- set compression level [default 6]
- --fast
- alias for -1
- --best
- alias for -9
If no file names are given, minilzip compresses or decompresses from standard
input to standard output. Numbers may be followed by a multiplier: k = kB =
10^3 = 1000, Ki = KiB = 2^10 = 1024, M = 10^6, Mi = 2^20, G = 10^9, Gi = 2^30,
etc... The bidimensional parameter space of LZMA can't be mapped to a linear
scale optimal for all files. If your files are large, very repetitive, etc,
you may need to use the
--match-length and
--dictionary-size
options directly to achieve optimal performance. For example,
-9m64
usually compresses executables more (and faster) than
-9.
Exit status: 0 for a normal exit, 1 for environmental problems (file not found,
invalid flags, I/O errors, etc), 2 to indicate a corrupt or invalid input
file, 3 for an internal consistency error (eg, bug) which caused minilzip to
panic.
