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.
