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 readable 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 dic-
       tionary size.

       lzmainfo is included in XZ Utils primarily for backward compatibility 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.
