Your call. But since it is in your home directory, it should already
be obvious that it is for you.

No. It searches for an executable file named "dothisnow".
Windows does that oddball "add an extension". In UNIX, what you
type is what is looked for.
Normally you do not end _commands_ in an extension saying what the
language is. Instead, for scripts the leading shebang line:
#!/bin/sh
tells the kernel what program will be used to run the script.
So you make a script and store it as "/home/user1/bin/dothisnow".
It starts with the line:
#!/bin/sh
When you issue the command "dothisnow a b c", if the kernel finds
your script it will execute the actual command:
/bin/sh /home/user1/bin/dothisnow a b c
getting the "/bin/sh" from the first line of the script.
In this way you can write scripts in different languages depending
on your needs, and make them up so that the kernel knows how to run
them.
As another example, a Python script would normally have a shebang line like:
#!/usr/bin/python

Yes.
