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

  1. When you use awk, grep is redundant:

    um=$(free -h | awk '/Mem/ { print $3 }')
