This is the first serious script that I can't figure out, I can't write a script for Astra Linux. All commands work individually, but not together

Answer 1

This "serious script" contains a set of simple commands. Run them in the same sequence as they run from a file and see where it fails. At the same time, pay attention to which user the script is run from and from whom you will run. You need to understand what is happening and this is the only right way. If they tell you what exactly is wrong, you will step on the same rake another time.

Answer 2

The NLog library will solve 99% of your tasks.

Answer 3

We are using the Enterprise Library . It allows you to implement a comprehensive solution for the project infrastructure, including logging, monitoring, status control, notifications, and a bunch of other usefulness.
The logging approach is described here .
There is also a library for ASP.NET called Elmah . There is a small article here.
