Users can use this
default user to login Cli to use IoTDB. The startup script of Cli is the start-cli script in the folder sbin. When executing the script, user should assign
IP, PORT, USER_NAME and PASSWORD. The default parameters are &quot;-h 127.0.0.1 -p 6667 -u root -pw -root&quot;.</p> <p>Here is the command for starting the Cli:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code># Unix/OS X

Before defining a timeseries, we should define a storage group using SET STORAGE GROUP, and here is an example:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; SET STORAGE GROUP TO root.ln
</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br></div></div><p>We can also use SHOW STORAGE GROUP to check created storage group:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; SHOW STORAGE GROUP
+-----------------------------------+
|                      Storage Group|
+-----------------------------------+
|                            root.ln|
+-----------------------------------+
storage group number = 1

When we create a timeseries, we should define its data type and the encoding scheme. We create two timeseries as follow:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; CREATE TIMESERIES root.ln.wf01.wt01.status WITH DATATYPE=BOOLEAN, ENCODING=PLAIN
IoTDB&gt; CREATE TIMESERIES root.ln.wf01.wt01.temperature WITH DATATYPE=FLOAT, ENCODING=RLE
</code></pre> <div class="line-numbers-wrapper"><span class="line-number">1</span><br><span class="line-number">2</span><br></div></div><p>To query the specific timeseries, use SHOW TIMESERIES &lt;Path&gt;. &lt;Path&gt; represents the path of the timeseries. Its default value is null, which means querying all the timeseries in the system(the same as using &quot;SHOW TIMESERIES root&quot;). Here are the examples:</p> <ol><li>Query all timeseries in the system:</li></ol> <div class="language- line-numbers-mode"><pre class="language-text"><code>IoTDB&gt; SHOW TIMESERIES
+-------------------------------+---------------+--------+--------+
