| 8 .SH NAME |
| 9 lzmainfo \- show infomation stored in the .lzma file header |
| 10 .SH SYNOPSIS |
| 11 .B lzmainfo |
| 12 .RB [ \-\-help ] |
| 13 .RB [ \-\-version ] |
| 14 .RI [ file ]... |
| 15 .SH DESCRIPTION |
| 16 .B lzmainfo |
| 17 shows information stored in the |
| 18 .B .lzma |
| 19 file header. It reads the first 13 bytes from the specified |
| 20 .IR file , |
| 21 decodes the header, and prints it to standard output in human |
| 22 readable format. If no |
| 23 .I files |
| 24 are given or |
| 25 .I file |
| 26 is |
| 27 .BR \- , |
| 28 standard input is read. |
| 29 .PP |
| 30 Usually the most interesting information is the uncompressed size and |
| 31 the dictionary size. Uncompressed size can be shown only if the file is |
| 32 in the non-streamed |
| 33 .B .lzma |
| 34 format variant. The amount of memory required to decompress the file is |
| 35 a few dozen kilobytes plus the dictionary size. |
| 36 .PP |
| 37 .B lzmainfo |
| 38 is included in XZ Utils primarily for backward compatibility with LZMA Utils. |
| 39 .SH EXIT STATUS |
| 40 .TP |
| 41 .B 0 |
| 42 All is good. |
| 43 .TP |
| 44 .B 1 |
| 45 An error occurred. |
| 46 .SH BUGS |
| 47 .B lzmainfo |
| 48 uses |
| 49 .B MB |
| 50 while the correct suffix would be |
| 51 .B MiB |
| 52 (2^20 bytes). |
| 53 This is to keep the output compatible with LZMA Utils. |
