Disk Space: Out of the overall size of 8.2G(8th arg) used is 2.1G(9th arg)and available is 6.2G(10th arg)

#The available disk space is $10 / $8

df -H | xargs | awk '{ print $10 "/" $8 }'

Here is the project implementation

CPU Utilization: free commands is used to show the utilization

#we need available /total ($13/$8)

COPY

free | xargs |awk '{print $13 "/" $8}'

#Show the top CPU processes, we use top command
