Hello. First of all, I think it is good to describe how I use SageMath before asking the question.
I installed SageMath in my laptop using Ubuntu 16.04. It is installed in directory "~/sage". I usually run SageMath in terminal. That is, I follow the following steps to run SageMath.
- Open the terminal (It is the basic terminal from Ubuntu 16.04).
- Go to the directory where SageMath is installed by typing "cd sage".
- Type "./sage". Then, sage session begins.
In sage session, I usually load a sage file which I already wrote and run it to check the result. But sometimes, a program does not seem to finish, since computation takes a lot of time. Then, I would like to finish the program which I am running now, but without going out of sage session, since otherwise, I should follow 3 steps above again. However, I could not find how to do it, yet.
Can anybody teach me how to do it?
