Hi!
I would recommend to run the commands manually, it would be better.
The first error is something related to the script you created and the use of >
The second (dnsmasq) is weired as the address is not being used or you are running the script for a second time.
For the apache issue use this command before starting it:
systemctl enable apache2

At the end of all it saids AP-ENABLED which means that the fake AP should be satrted, but the other errors might be interfering with it.

Let me know how it goes!
