Use %hostname% of the remote host in a script

Hello,

I'm currently working on a script to save the startup configuration on my switch to our local server.

I would like to save my log with this format after the copy:
where "name of the switch" is a variable pickup automatically like %hostname% for example.
%hostname% doesn't work here so is there any preconfigured variable that does this job?
If no, is there a way to create one?

Thanks for your help,
Best regards.

So how do you provide the hostname to the connection settings? (the open command)
Provide the hostname to the get command the same way.
If you want more specific help, please post your complete script.
