Question giving up for now...
Here is what I have managed to come up with:

Code:
#!/bin/sh
cp ch25.txt ch25.fn.tex
n=`grep -c '^\[' ch25_footnotes.txt`
echo $n

#for i in {1..n};  ### This syntax was not working, for some reason

for ((i=1; i <= n ; i++))
do
        str="grep '^\[$i\]' ch25_footnotes.txt > temp"
#      echo $str
        eval $str
        r=`awk -F] '{print $2}' temp`
#      echo $r ## Up to here, things work as expected.
        str2="sed 's/\[$i\]/\\\footnote{$r}/' ch25.fn.tex"
        eval $str2
done

Now, the issue seems to be that it is dumping to standard output, rather than actually editing ch25.fn.tex. I dont really know why thats happening... and I THINK that it printed to stout 140 times, each with the footnote added to only that one number... I THINK that is what happened. To much output to sift through. I feel that I have narrowed down the problem to my sed command.

I have spent too much time playing around already. I hope someone finds this interesting or is sympathetic to my curiosity and helps me out!
