By using the -e parameter, you can operate IoTDB without entering the client's input mode.</p> <p>In order to avoid confusion between statements and other parameters, the current situation only supports the -e parameter as the last parameter.</p> <p>The usage of -e parameter for Cli/shell is as follows:</p> <div class="language- line-numbers-mode"><pre class="language-text"><code> Shell > ./sbin/start-client.sh -h {host} -p {port} -u {user} -pw {password} -e {sql for iotdb} |
