> We added the -e parameter to the start-client.sh script. By using the -e
> parameter, we can operate IoTDB in the shell without entering the client's
> input mode. Take following as an example:
> Suppose we want to create a storage group root.demo to a newly launched
> IoTDB, create a timeseries root.demo.s1 and insert three data points into it.
> With -e parameter, we could write a shell like this:
> {code:java}
> # !/bin/bash
> host=127.0.0.1
> port=6667
> user=root
> pass=root
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "set
> storage group to root.demo"
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "create
> timeseries root.demo.s1 WITH DATATYPE=INT32, ENCODING=RLE"
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "insert
> into root.demo(timestamp,s1) values(1,10)"
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "insert
> into root.demo(timestamp,s1) values(2,11)"
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "insert
> into root.demo(timestamp,s1) values(3,12)"
> ./start-client.sh -h ${host} -p ${port} -u ${user} -pw ${pass} -e "select s1
> from root.demo"
> {code}
> The print results are shown in the figure, which are consistent with the
> client and jdbc operations.

> It should be noted that the use of the -e parameter in shell scripts requires
> attention to the escaping of special characters. In order to avoid confusion
> between statements and other parameters, the current situation only supports
> the -e parameter as the last parameter.
