A Tip

turkshead shares a time saver:  

Shell loops. You run a loop in the shell with like

for i in {1..50}; do [stuff]; done

And it just does [stuff] 50 times. If you’ve got 50 hosts you want to run some random commands on, just figure out the command line on a test host, add quoting, and wrap it in a for loop. You can add | tee filename.log to capture the output.

For bonus points, use parallel and it all happens at once.

Another Free Tool

Zellij is a terminal workspace with the base functionality of a terminal multiplexer that also allows users to extend it and create a personalized environment with panes laid out exactly as desired when they start the app. spidernik84 says, “Nowadays i suggest trying Zellij over tmux. It’s pretty cool especially for newstarters.”
