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 decompress the file is a few dozen kilobytes plus the dic‐
tionary 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.
