| .SH SYNOPSIS | |

| .RI [ file ]... | |
| .SH DESCRIPTION | |
| .B lzmainfo | |
| shows information stored in the | |
| .B .lzma | |
| file header. | |
| It reads the first 13 bytes from the specified | |
| .IR file , | |
| decodes the header, and prints it to standard output in human | |
| readable format. | |
| If no | |
| .I files | |
| are given or | |
| .I file | |
| is | |
| .BR \- , | |
| 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 | |
| .B .lzma | |
| format variant. | |
| The amount of memory required to decompress the file is | |
| a few dozen kilobytes plus the dictionary size. | |
| .PP | |
| .B lzmainfo | |
| is included in XZ Utils primarily for | |
| backward compatibility with LZMA Utils. | |
| .SH "EXIT STATUS" | |
| .TP | |
| .B 0 | |
| All is good. | |
| .TP | |
| .B 1 | |
| An error occurred. | |
| .SH BUGS | |
| .B lzmainfo | |
| uses | |
| .B MB | |
| while the correct suffix would be | |
| .B MiB | |
| (2^20 bytes). | |
| This is to keep the output compatible with LZMA Utils. | |
