.TH CLZIP "1" "January 2019" "clzip 1.11" "User Commands"
.SH NAME
clzip \- reduces the size of files
.SH SYNOPSIS
.B clzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Clzip is a C language version of lzip, fully compatible with lzip 1.4 or
newer. As clzip is written in C, it may be easier to integrate in
applications like package managers, embedded devices, or systems lacking
a C++ compiler.
.PP
Lzip is a lossless data compressor with a user interface similar to the
one of gzip or bzip2. Lzip can compress about as fast as gzip (lzip \fB\-0\fR)
or compress most files more than bzip2 (lzip \fB\-9\fR). Decompression speed is
intermediate between gzip and bzip2. Lzip is better than gzip and bzip2
from a data recovery perspective. Lzip has been designed, written and
tested with great care to replace gzip and bzip2 as the standard
general\-purpose compressed format for unix\-like systems.

set compression level [default 6]
.TP
\fB\-\-fast\fR
alias for \fB\-0\fR
.TP
\fB\-\-best\fR
alias for \fB\-9\fR
.TP
\fB\-\-loose\-trailing\fR
allow trailing data seeming corrupt header
.PP
If no file names are given, or if a file is '\-', clzip 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...
Dictionary sizes 12 to 29 are interpreted as powers of two, meaning 2^12
to 2^29 bytes.
.PP
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 \fB\-\-dictionary\-size\fR and \fB\-\-match\-length\fR
options directly to achieve optimal performance.
.PP
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 clzip to panic.
