.TH LZMAINFO 1 "30 May 2005" "LZMA utils"
.SH NAME
lzmainfo \- show infomation stored in the LZMA compressed file header
.SH SYNOPSIS
.B lzmainfo
[
.B \-\-help
|
.I filename
]
.SH DESCRIPTION
.B lzmainfo
shows information stored in the LZMA compressed file header. It reads
the first 13 bytes from the specified
.IR filename ,
decodes the header and prints it to the standard output in human
readable format. If no
.I filename
is specified, the standard input is read.
.PP
Usually the most interesting information is the uncompressed size and
the dictionary size. Uncompressed size can be shown only if the file is
in the non-streamed LZMA format. The amount of memory required to
decompress the file is a few kilobytes plus the dictionary size.
.SH DIAGNOSTICS
.B lzmainfo
returns zero on success and non-zero on error.
