A case for Tmux tool

Terminal Multiplexer:

The below is a case using in my usual works:

"

tmux new-window -n foo "sshme jumpbox1"
tmux selectp -t 0 # select the first (0) pane
tmux splitw -v  -t 0 "ssh -l user1 jumpbox2"    # split it into two halves
tmux selectp -t 1 # select the new, second (1) pane
tmux splitw -h -t 1 "sshme jumpbox3"
tmux select-pane -t 0
"

The result as below:

you can operations in three terminals at the same time .

the switch shortcut:

C + b+q , then select the panel number.
