How to get access of process running on one terminal from other terminal in Linux?

Question

I want to know the procedure so that i can access or get control from terminal over the process running on some other terminal in Linux .

• Both terminals belong to same system .

Solution 1

Pehaps you want something like reptyr? (https://github.com/nelhage/reptyr)

You simply type reptyr PID to 'gain control' of another process (like vim or whatnot).

Edit:

This question has more information on using screen or tools like reptyr.

Solution 2

Use the screen utility to start any process from terminal, so that you can access the same process from any other terminal either locally or remotely. For instance:

From first terminal

1. Start a screen using screen -dR test and hit Enter, you will get shell within in screen.
2. Run you program here

From second terminal

1. Get in to existing screen using screen -x test

Now you should be able to see process running on first terminal, and will have the full control over that process.

You can investigate more on screen utility… its a very useful tool for any system administrator.

Hope the above tip will help you.

There is no such thing as taking control of some process already running. The most similar thing is using screen as described by abhi_ksd.

Given @onionjake's answer, this is a great question.
