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  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.
