How to write in bash to ssh to different machine and create tmux session then run some command in it

  • 772

Basically I want to write some script like

#!/bin/bash
for idx in 1 2 3 4 5 6
do
        ssh machine$idx tmux new-session -d -s "myTempSession$idx" python run.py
done

which can do the thing separately on each machine as:

ssh machine$idx 

tmux new-session -d -s "myTempSession$idx"

python run.py

but after many trial and error, I still cannot make it work as expected.

ssh bash tmux

    You should divide the two actions 1) create a tmux detached session; 2) send a command/keys to it. Also maybe adding the -n option is a good idea... So your script should look like as:

    #!/bin/bash
for idx in 1 2 3 4 5 6
do
    ssh -n machine$idx 'tmux new-session -d -s "myTempSession$idx"; tmux send-keys -t "myTempSession$idx" "python run.py" ENTER'
done
