a more general free-memory command

[小明同学 <a....@foxmail.com>]

Hi all,


	I fail to use the following command to free memory because the colon in the command does not match the colon used in the Chinese system.


	> free -m | awk '/:/ {print $2;exit}'


	I come out with a solution that matches the position instead of the colon:


	> free -m| sed -n '2p' | awk '{print $2}'


	I also find that similar commands are used in the IoTDB conf/iotdb-env.sh, so I suggest they be modified.


	Hope you find this helpful.


Bests,
Zhengming Zhang
