Question

Operating Systems

A programming language for automating the administration of win / linux operating systems ...
Perhaps you are already using something, but if you could instantly retrain to another PL?
Cross-platform is important.

Answer 1

How do you imagine cross-platform administration of Windows and Linux, if they have completely different internals? Automatic installation of drivers in Windows and Linux are two different things.
Many things in the windows network are set centrally through global policy, which Linux has no idea about.
Again, installing software is different.
In principle,
For Linux, of course, the best is bash
For Windows - powershell / bat
You can put git on windows so that bash scripts work.
But anyway, for a number of tasks, it will be necessary to make conditional transitions in scripts and call either sysinternals and powershell for windows, or gnu / bash with sudo on Linux.
For banal things - bash/python/perl should be more than enough, but it's not so much administration automation as general automation.

Answer 2

python + ansible

Answer 3

ruby or python
the first allows you to write shorter, the second is friendlier for those who are not professional developers

Answer 4

perl. Easy to install on Windows, default on Linux.
