I'm not the most experienced individual when it comes to Linux or its commands, but let's say I wanted to launch a program and run multiple expressions on its text output, all of which output to a live buffer. How might I do this and separate each expression's output to a separate buffer or separate terminal?

I could probably figure out how to output to separate files, but I want each filter updating in real-time and isolated (not cluttered by the other filters' outputs).
Also, is there any way I can remove a segment of text from the beginning of each line? I haven't looked into that at all yet.

You could dump the raw output to a logfile and run several 'tail -f's piped to appropriate greps or seds or awks or such.

Thank you for the speedy response
That could work, but there's something else that I'd prefer to do if at all possible.
Am I able to pipe ALL output from one terminal into two others? And if so, could I have two different grep expressions running in each destination terminal? I'm using the terminator terminal, by the way, but if there is a universal solution, that'd be fantastic.

Yes, you can use tail -f from multiple terminals and use separate grep expressions on each one if you wanted to. Linux is too versatile to only have one solution.
