In fish, the following is a valid command.
{
echo Testing.
}
So I put that command into a "Test.txt" text file.
And in a terminal window, I entered the following.
{
exec <Test.txt
}
Resulting in the following screen output.
{
exec -- execute command in current process
Synopsis
exec COMMAND [OPTIONS...]
Description
exec replaces the currently running shell with a new command. On
successful completion, exec never returns. exec cannot be used
inside
a pipeline.
Example
exec emacs starts up the emacs text editor, and exits fish. When
emacs exits, the session will terminate.
}
What is the appropriate way to take instructions from a file, and do them?

Yes, that worked fine!
