LZMAINFO(1)                         XZ Utils                         LZMAINFO(1)

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 decom-
     press the file is a few dozen kilobytes plus the dictionary 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.
