https://docs.saltstack.com/en/getstarted/fundamentals/remotex.html :

"Salt lets you remotely execute shell commands across multiple
systems using cmd.run:

salt '*' cmd.run 'ls -l /etc'

All managed systems simultaneously and immediately execute this
command and then return the output to the Salt master.
