Alright, so this was an uninteresting problem, I guess... no hits at all except for my own! But, I did solve PART of the problem, so for what its worth I am going to explain that... I am sure I am not the only person to make this mistake.

In my grep command, I was trying to reference a variable integer stored in $i.
Grep was reading the $ independently, as a regular expression meaning "at the end of the line" I think... but at any rate, it was NOT looking for the variable $i and passing that into the argument.

To work around this:
Code:
for i in {1..5}
do 
    echo $i; #to make sure the for loop was working as expected.
    
    str="grep '^\[$i\]' ch25_footnotes.txt"; #I saved the whole thing as a string, which DOES 
                                             #interpret $i as a variable.  If I were to echo that 
                                             #command, it would have a number there 
                                             #rather than a $i.
   
    eval $str; #this actually runs the grep command
done

This works for the grep part... But I guess now the kink is in getting the for command to acknowledge the $n variable... Smilie

Meh... help would be welcome!
