# linux demo
|
||||
|
||||
## What
|
||||
|
||||
KVDB and TSDB demo on linux platform
|
||||
|
||||
## How
|
||||
|
||||
### Step1: build
|
||||
|
||||
Run `make` command on terminal. The generated executable program is located in the `out` folder.
|
||||
|
||||
### Step2: run demo
|
||||
|
||||
Switch to the `out` folder. Then run the `./FlashDBLinuxDemo` file multiple times.
|
||||
|
||||
### Step3: check the log
|
||||
|
||||
This demo's log will output to terminal.
