NAME
     lzmainfo - show information stored in the .lzma file header

SYNOPSIS
     lzmainfo [--help] [--version] [file]...

DESCRIPTION
     lzmainfo  shows information stored in the .lzma file header.
     It reads the first 13 bytes from the specified file, decodes
     the  header, and prints it to standard output in human read-
     able format.  If no files are given or file is  -,  standard
     input is read.

     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
     variant.  The amount of memory required  to  decompress  the
     file is a few dozen kilobytes plus the dictionary size.

     lzmainfo is included in XZ Utils primarily for backward com-
     patibility with LZMA Utils.

EXIT STATUS
     0    All is good.

     1    An error occurred.

BUGS
     lzmainfo uses MB while the correct suffix would be MiB (2^20
     bytes).   This  is  to  keep the output compatible with LZMA
     Utils.
