Lots of content was updated on the xz man page. Technical improvements: - Start a new sentence on a new line. - Use fairly short lines. - Use constant-width font for examples (where supported). - Some minor cleanups. Thanks to Jonathan Nieder for some language fixes.

.SH DESCRIPTION
|
|
.B lzmainfo
|
|
shows information stored in the
|
|
.B .lzma
|
|
file header.
|
|
It reads the first 13 bytes from the specified
|
|
.IR file ,
|
|
decodes the header, and prints it to standard output in human
|
|
readable format.
|
|
If no
|
|
.I files
|
|
are given or
|
|
.I file
|
|
is
|
|
.BR \- ,
|
|
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
|
|
.B .lzma
|
|
format variant.
|
|
The amount of memory required to decompress the file is
|
|
a few dozen kilobytes plus the dictionary size.
|
|
.PP
|
|
.B lzmainfo
|
|
is included in XZ Utils primarily for
|
|
backward compatibility with LZMA Utils.

|
|
All is good.
|
|
.TP
|
|
.B 1
|
|
An error occurred.
|
|
.SH BUGS
|
|
.B lzmainfo
|
|
uses
|
|
.B MB
|
|
while the correct suffix would be
|
|
.B MiB
|
|
(2^20 bytes).
|
|
This is to keep the output compatible with LZMA Utils.
