.SH NAME
lunzip \- decompressor for lzip files
.SH SYNOPSIS
.B lunzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Lunzip is a decompressor for lzip files. It is written in C and its
small size makes it well suited for embedded devices or software
installers that need to decompress files but do not need compression
capabilities. Lunzip is fully compatible with lzip\-1.4 or newer.
.PP
Lunzip provides a 'low memory' mode able to decompress any file using as
little memory as 50 kB, irrespective of the dictionary size used to
compress the file. To activate it, specify the size of the output buffer
with the '\-\-buffer\-size' option and lunzip will use the decompressed
file as dictionary for distances beyond the buffer size. Of course, the
smaller the output buffer size used in relation to the dictionary size,
the more accesses to disk are needed and the slower the decompression is.
This 'low memory' mode only works when decompressing to a regular file.
.SH OPTIONS
.TP
\fB\-h\fR, \fB\-\-help\fR
display this help and exit
.TP
\fB\-V\fR, \fB\-\-version\fR
output version information and exit
.TP
\fB\-c\fR, \fB\-\-stdout\fR
send output to standard output
.TP
\fB\-d\fR, \fB\-\-decompress\fR
decompress (this is the default)
.TP
\fB\-f\fR, \fB\-\-force\fR
overwrite existing output files
.TP
\fB\-k\fR, \fB\-\-keep\fR
keep (don't delete) input files
.TP
\fB\-o\fR, \fB\-\-output=\fR<file>
if reading stdin, place the output into <file>
.TP
\fB\-q\fR, \fB\-\-quiet\fR
suppress all messages
.TP
\fB\-t\fR, \fB\-\-test\fR
test compressed file integrity
.TP
\fB\-u\fR, \fB\-\-buffer\-size=\fR<bytes>
set output buffer size in bytes
.TP
\fB\-v\fR, \fB\-\-verbose\fR
be verbose (a 2nd \fB\-v\fR gives more)
.PP
If no file names are given, lunzip 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...
.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 lunzip to panic.
