Ditto. I posted (here: https://news.ycombinator.com/item?id=42881123 https://news.ycombinator.com/item?id=42881123 ) about them and other options: To send the same command to multiple servers, use pdsh: https://linux.die.net/man/1/pdsh https://linux.die.net/man/1/pdsh To collect all the results and show which ones are the same or different, use dshbak (i.e., "pdsh <parameters including servers>|dshbak"): https://linux.die.net/man/1/dshbak https://linux.die.net/man/1/dshbak Similar things, sometimes more convenient but less efficient for a large number of servers, are to use the konsole terminal program and link multiple window tabs together so the same typed command goes to all, and quickly view the results across the tabs; or to use tmux and send the same commands to multiple windows (possible useful "man tmux" page terms: link-window, pipe-pane, related things to those, activity, focus, hooks, control mode). And others that I haven't used but which also look possibly interesting for platforms where pdsh and dshbak might not be available (like OpenBSD at least): - https://github.com/duncs/clusterssh/wiki https://github.com/duncs/clusterssh/wiki (available on OpenBSD as a package) - https://www.gnu.org/software/parallel/ https://www.gnu.org/software/parallel/ (also available as a package on OpenBSD 7.6: named "parallel-20221122"; might relate to "pdksh") - Also clusterit.
