lzmainfo - show information stored in the .lzma file header


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


   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
   dictionary size.

   lzmainfo is included in XZ Utils primarily for  backward  compatibility
   with LZMA Utils.


   0      All is good.

   1      An error occurred.


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