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 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 (2ˆ20 bytes). This is to keep the output compatible with LZMA Utils.
