It is confusing and I appreciate your help and decrypting my request. Let me just add a little more explanation. When I originally referred to the "bar_txt" file - that's a file containing a list of /etc/passwd entries. The "foo_txt" file contains the name of the server where the /etc/passwd entry will be created. So, I usually have a "foo_txt" file that has repeating entries depending on how many lines of the bar_txt file will be input to the respective file created from foo_txt. I tried to denote this as the server name is listed in each line of the bar_txt file - it would be where you see "file_a" or "file_b" etc. I probably could have written the question a little better.

In any event I appreciate your reply and I'll give it a chance when I can - just thought I'd throw up a quick post and see if I could get some guidance.
