1. NAME

lzmainfo - show information stored in the .lzma file header

2. SYNOPSIS

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

3. 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

R - , 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.

4. EXIT STATUS

0

    All is good.

1

    An error occurred.

5. BUGS

lzmainfo uses

MB while the correct suffix would be

MiB (2^20 bytes). This is to keep the output compatible with LZMA Utils.
