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.
