Using tee command for one command at once

I am new to using the team tee.

I try to run one of my programs, which takes a lot of time, but it prints information as it moves. I use "tee" to save the output to a file, and also to view the output in a shell ( bash).

But the problem teedoes not redirect the output to the shell until the end of my command. Is there any way to do this?

I use Debian and bash.

Proper use of the tee command and seems to work. Replace the part in front of the pipe with your team and you should be good to go.
