Q:

How can I see the running time of the terminal? (Ubuntu user)

So I began working in terminal (with tmux) this morning and forgot the hour when I began. I need to know the time when I started the terminal (or tmux) or the running time of the terminal (or tmux).
Can anyone help? Thanks.

A:

ps -eo '%t %c' | grep tmux

should give you the running time of your tmux. Of course, you can also grep for your terminal process directly.
