I believe to solve real life problem in a simple way that can save time and money of organization bey implementing automation tools. Join with me on my in this journey in DevOps world.
This mini project will show the current username, date and time and Disk space and RAM utilization details.
✦ Welcome the user, show the current username
✦ Show the date and time
✦ Show the uptime of the server and the last logins
✦ Show the disk space and RAM utilization
✦ Show the top CPU processes
we will create a .sh file in which all script will be incorporated and then we execute .sh file and we will provide execute permission by below commands.
Commands to create a script file.
COPY
touch script.sh
chmod +x <filename.sh> //filename is script.sh
#To display the current user we use the below command
COPY
whoami
#command which shows the date and time
COPY
date
#uptime command is used to find out how long the system is active (running)
COPY
uptime
#to find the last login details we use last command
COPY
last
#memory command which gives details about disk space
COPY
df -H
#memory command which gives details about RAM
COPY
free
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
COPY
top
Below are the script written in myfirst.sh script file.
