That's right, "for" executes the "do" part once for each word in
between "in" and ";". So the above for loop is the same as:

bash$ for f in This is line1 
bash> This is line2 
bash> This is line3 ;
bash> do echo $f ; done

Since for doesn't care about newlines, this is the same as:

bash$ for f in This is line1 This is line2 This is line3 ; do echo $f ; done

I can think of a bunch of ways, but they're all really convoluted, and
mostly involve using either "for" or "cat" in rather trivial
ways. What exactly are you trying to do? There is probably a better
way than using both "for" and "cat".
