In my organisation we have a few tools.
For more complex command sets I use ansible scripts to push commands to a defined set of hosts (sometimes based on conditions within the device itself).
For simple command sets where there are only a few mines at most, I use a network management software called NeDi. You configure NeDi with credentials for your devices and it can SSH/Telenet into them and execute the commands you want and show you output. I recently used it to change SNMP contact on over 300 cisco switches for example.
Both of these will take a little time to initially setup but will save time in the future.
