Task $2$: The objective of this task is to enhance the students' ability in using Bash$/$Unix

commands and deploying them in real$-$life scenarios. $[9$ marks$]$

You will write a bash script that simulates the collection of data from two home sensors: the gas

sensor and the temperature sensor:

A$.$ Create a directory named "Sensor$\_$Dtata" in the home directory. $[1$ mark$]$

B$.$ Inside the "Sensor$\_$Dtata" directory, create two files for collecting the sensors$"$ data

separately. Name your files as: "Gas$\_$Sensor$\_$Datatat" and

"Temperature$\_$Sensor$\_$Data.txt$".[1$ mark$]$

C$.$ Using the command line, write, in the two sensors$\text{'}$ files, $20$ values, that fall between $0$ and

Save the changes in the files. $[1$ mark$]$

D$.$ Write a script that reads the values stored in the sensor$\text{'}$s files. Your script needs to be an

executable file. $[1$ mark$]$

E$.$ Set$-$up your script to be called in two cases:

Your script needs to run automatically at regular intervals, on three days of the week

$($Monday$,$ Tuesday and Wednesday$)$ at $2a.m.$ in the morning because you have long

outdoors duty on these three days. $[2$ mark$]$

Your script needs to run after one hour. For this purpose, use crontab command.

$[2$ mark$]$

F$.$ On the command line, run proper commands to find the two sensor files among other txt

files in the home directory. $[1$ mark$]$
