.TH PDLZIP "1" "May 2015" "pdlzip 1.6" "User Commands"
.SH NAME
pdlzip \- reduces the size of files
.SH SYNOPSIS
.B pdlzip
[\fI\,options\/\fR] [\fI\,files\/\fR]
.SH DESCRIPTION
Pdlzip \- A "public domain" version of the lzip data compressor
also able to decompress legacy lzma\-alone (.lzma) files.
Lzma\-alone is a very bad format. If you keep any lzma\-alone files, it is
advisable to recompress them to lzip format.
.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
.TP
\fB\-f\fR, \fB\-\-force\fR
overwrite existing output files
.TP
\fB\-F\fR, \fB\-\-recompress\fR
force re\-compression of compressed files
.TP
\fB\-k\fR, \fB\-\-keep\fR
keep (don't delete) input files
.TP
\fB\-m\fR, \fB\-\-match\-length=\fR<bytes>
set match length limit in bytes [36]
.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\-s\fR, \fB\-\-dictionary\-size=\fR<bytes>
set dictionary size limit in bytes [8 MiB]
.TP
\fB\-t\fR, \fB\-\-test\fR
test compressed file integrity
.TP
\fB\-v\fR, \fB\-\-verbose\fR
be verbose (a 2nd \fB\-v\fR gives more)
.TP
\fB\-1\fR .. \fB\-9\fR
set compression level [default 6]
.TP
\fB\-\-fast\fR
alias for \fB\-1\fR
.TP
\fB\-\-best\fR
alias for \fB\-9\fR
.PP
If no file names are given, pdlzip 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 \fB\-\-match\-length\fR and \fB\-\-dictionary\-size\fR
options directly to achieve optimal performance. For example, \fB\-9m64\fR
usually compresses executables more (and faster) than \fB\-9\fR.
.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 pdlzip to panic.
