Until recently, I used tmux occasionally, only if I had to run some experiments on a remote server and later see the results of the execution. Basically, I used it only as a mean to execute commands in the background. If I needed to run several commands on a remote server parallelly, I used to open several terminals, connect each of them to the remote host and then switch between them.
Recently, I started working with a remote server through ssh more often and the routine, I used to, became very operation consuming. So, to improve my effectiveness, I spend several hours reading articles, watching videos and trainings how to use tmux. This article combines the knowledge I have acquired. It is also a crib for me if I forget something in the future.
