#### 1. What about this tool to do?
> use lua to parse rdb file to user's format data, like aof file, json etc.
#### 2. How to use?
```shell
$ cd rdbtools/src
$ make
$ ./rdbtools -f ../tests/dump2.4.rdb -s ../scripts/example.lua
```

#### 3. Options
```shell
USAGE: ./rdbtools [-f file] -V -h
-V --version
-h --help show usage
-f --file specify which rdb file would be parsed.
-s --file specify which lua script, default is ../scripts/example.lua
```
If you want to handle key-value in rdb file, you can use `-s your_script.lua`, and lua function `handle` will be callbacked.
Example can be found in `scripts/example.lua`, and it just print the key-value.
##### Json format example
`cat scripts/json_exapmle.lua`
```lua
local cjson = require "cjson"
function handle(item)
print(cjson.encode(item))
end
```
And result is below:

function handle(item)
--item.type, value may be string, set, zset, list, or hash.
--item.expire_time, key expire time .
