OK, I just want to be clear. In your example, it looks like you are pointing the script directly to the files, rather than a filelist. Is this correct?

---------- Post updated at 05:44 PM ---------- Previous update was at 05:24 PM ----------

OK, I fixed the file names, which is something I wanted to do anyway:
Code:
find ./02_New\ Testament -name "*txt" -type f -depth 2 |rename 's/(?<=[a-z])(?=[0-9]\.txt)/0/g'

Then I generated new file lists, and edited the lists so that they were properly escaped:
Code:
perl -pi -e 's/ /\\ /g' NTfilelist.txt

Now we have a perfectly formed listfile! Let's concatenate using Bakunin's solution!
Code:
-bash $ rm resultfile ; while read num file ; do cat $file >> resultfile ; done <./OTlistfile.txt
rm: resultfile: No such file or directory
-bash: ./OTlistfile.txt: No such file or directory

OK, clearly I'm missing something. I don't know why it can't find my listfile - OTlistfile.txt I tried it a couple of different ways, with a ./, etc.
Also, I thought resultfile would be created. Do I need to create an empty file for it to work with? You guys gotta remember, I really know nothing. You must explain as to an overgrown child.
A word to Bakunin as to my use of perl as a regex engine:
Possibly, I am killing flies with cannons, but when I began learning regex, I found out, much to my dismay, that every app understood regexes differently. So, I learned it for grep, (which also has the -P flag), and for perl. In other words, I use perl because I know how to write regexes for it, and I'm never clear what other apps will understand.

BUGS

       The  network  synchronization between client and server instances is weak, and does not prevent incompatible options from being used on the
       two instances.  The method used for retrieving work completions is not strictly correct, and race conditions may  cause	failures  on  some
       systems.
