Most of the times, after helping friends to solve their problems, they ask me “How I did it”. Then I thought if they can see what I am typing, then it will be easier for them to understand the steps.
For the same I started using screen command.
First login to the client’s machine via ssh
After login we need to create a screen session and named it to techsupport
screen -S techsupport
Now i will instruct my friend to take the same session via screen on the machine I logged in via ssh
screen -x techsupport
Now me and my friend using a common screen, whatever command I run over screen he can able to see them.
