How To Make IoT Messaging with BashShell

Create new file with extension .sh ..
As you know the first line of Bash Script start with this

#!/bin/bash

okay, let's say we want collect information of our IoT like Memory and IP Address etc..
so we can collect this information with Shell Script.

# Get Used Memory
um=$(free -h | grep Mem | awk ' { print $3 } ')
# Get Free Memory
fm=$(free -h | grep Mem | awk ' { print $2 } ')
# Get Local IP Address
ipadd=$(ifconfig wlp3s0b1 | grep 'inet ' | awk '{print $2}')
# Get Public IP Address
pip=$(curl iblo.esy.es)

Okay We Are Done, We collect all information that we need to save, so we need name for our IoT, let's make it complex .

IoTName="rasp5289166"

Now we put all Variables in one Variable

URL="http://www.iblo.esy.es/save/data/?iot=$IoTName&PuIp=$pip&ip=$ipadd&UsedMem=$um&FreeMem=$fm"

Now let's Save our Data

output=$(curl -X POST $URL)

the output variable should be like this :

New Name http://www.iblo.esy.es/load/data/?iot=rasp5289166

Note it respond with "New Name" and the link of your saved data.
if we save data again the output looks like this :

Overwritten http://www.iblo.esy.es/load/data/?iot=rasp5289166
