In the manual for example there are several example command lines or functions having multiple lines. I still don't understand whether these are supposed to called individually (i.e. one at a time), or may be called simultaneously by the use of shift + return keys at each line end and executed with a final return key?
One at a time.

Nowhere, is there an explanation of how to state the path for the log file
You can put it in your home directory, or under /var/log, or maybe in /tmp or wherever you're comfortable. It doesn't really matter. Just don't put it in a part of your filesystem that resides on the device that you're using as the origin with ddrescue (which can't happen, anyway, if you unmount the origin as you always should).

To clarify: if you want to copy /dev/sdx to a new drive, and if on /dev/sdx there's the "/home" partition, you login as root (the home of root is /root, so it's not under /home), then unmount /dev/sdx, and as a log file you can use for instance /root/ddrescuelog, or /var/log/ddrescuelog. Surely you don't want to use something like /home/Royalist/ddrescuelog, because:
a) if you did unmount /dev/sdx, as suggested, /home/Royalist would no more be there;
b) if you didn't unmount /dev/sdx, ddrescue - writing its log - would modify the origin while copying it (never a good idea).

I think you were overthinking it a touch. The synopsis pretty much says it all:
Code:
ddrescue [options] infile outfile [logfile]

The [ ] surround things which are optional, which leave you with

Code:
ddrescue infile outfile

which does pretty much what you'd think.
