It reads the first 13 bytes from the specified .IR filename , decodes the header and prints it to the standard output in human readable format. If no .I filename is specified, the standard input is read. .PP 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. The amount of memory required to decompress the file is a few kilobytes plus the dictionary size. .SH DIAGNOSTICS .B lzmainfo returns zero on success and non-zero on error. .SH AUTHORS .B lzmainfo is part of the LZMA utils written originally for the Tukaani Linux by Lasse Collin . .br http://tukaani.org/lzma/ .PP .B lzmainfo contains code from the LZMA SDK written by Igor Pavlov. .br http://7-zip.org/sdk.html .SH SEE ALSO .BR lzma (1), .BR lzmadec (1)
