For people who use the terminal on a daily basis, multiple terminals really help. Over time we start to have a certain setup that we call home for multiple reasons: debugging, application development, configuring, etc… This is where tmux comes in. Sure there is also the program called “screen” but thats for another post.

Cool stuff

C-a : setw synchronize-pages on
C-a "

This will sync all of the pages on a window to allow you setting up multiple terminal sessions with the same commands. This is helpful when you want to have multiple terminals login to the same box (Perhaps for editing a config file and another terminal for stoping or starting services. Throw in another one for monitoring logs.)


At the time of this article, I had to have ruby 1.9.3 to install tmux by using the following command:

yum install tmux
