Here is exactly this plugim which I'm trying to use.
I'm copying it into text file with .sh extension

I have another question. Inform OS v2.3.1 which is highlighted in description is the only one which can be monitored or I can use it, for example with for storage with v3.1.2?

You may have used vi to create the file, but if you copy/pasted from a windows editor into vi then you also copy/pasted Windows line endings into a UNIX script.

Also to be clear by vi I assume you mean vim. There is a large difference for many things.

Please run the dos2unix referenced earlier or use vim itself to correct the errors: Save and exit the file. Try running it again.
