Question

i want to run some command on several machine using ssh. I know it can be done by just using the command “ssh user@hostname command”. However, the command i want to run print some string on the console. Is there any way that send all the strings back to the console that i’m on?

Answer 1

You could run the commands in a screen:

screen -S test
ssh user@hostname command1
ssh user@hostname2 command2

You can then detach (Ctrl-D) from the screen, let it run for however long it will run, then re-attach (screen -r test) to the screen and see all of the output. This assumes that you won’t have a ton of output from the commands, however. Here’s a link to a tutorial on screen.
