| .SH NAME |
| lzmainfo \- show information stored in the .lzma file header |
| .SH SYNOPSIS |
| .B lzmainfo |
| .RB [ \-\-help ] |
| .RB [ \-\-version ] |
| .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. |
