I'm creating a script for users to run. I need to redirect the output to a file I'm creating from inside the script (hostname-date).
I have all the pieces except for how to copy the output of the script from inside the same script. All the examples I can find call the script and > it into the log, but this isn't an option.

Add the following at the top of your script:
exec &> output.txt
It will make both stdin and stderr of the commands in the rest of your script go into the file output.txt.
exec in bash allows you to permanently redirect a FD (say, stdout) to a file.
A shell that calls a shell.
Have the first shell create the variable (hostname-date) and call the second shell redirecting the output to the file.
