Nested while read line loop

Sorry for the short info 
: im using the ksh on a sun/solaris and the input data is as following:
To describe the input data is quite complicated, but in a nutshell : I have a a flat-ascii file which contains directory-names. This file I want to read and with every red file, I'm reading the directories on an ftp-site. Then conditionally, after executing an Oracle-database package another text file is written (by this package). This is also a flat file with every line containing a path-name and jpg-filename. In the second read I have to create the path and copy the jpg-file. I hope its a little more clear now. The sollution of Jim is perfect, but I was just curious if I could make a nested while loop reading files...
Thanx for your replies and greetings,
Rakker

mrename - program to rename files SYNOPSIS
mrename 'pattern' prefix [option] DESCRIPTION
This manual page documents briefly the mrename command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page. mrename is a tool for easy and automatic renaming of many files. The 'pattern' is the pattern to search files to rename (quoted to avoid that bash resolve it), and prefix is the prefix that will be added to the name of each file. The two alternative options for copying or moving files in the new name are explained below. All parameters are needed, and you have to stay and launch the script in the same direc- tory of the files to be renamed. The program should be able to write in this directory. OPTIONS
There are only the following three options. -c The option -c will copy each file with the new filename. -m The option -m will move each file in the new filename. -h Display help. EXAMPLE
If you have a directory with two jpeg images prof.jpg and forp.jpg and you want to add them a prefix like item0, item1 etc.. (that is item0prof.jpg, item1forp.jpg etc..) do this: cd /path/to/the/images mrename '*.jpg' item -c to copy each matching file into another with the new name mrename '*.jpg' item -m to rename each file without keeping a copy with the previous name Word-Wide-Web: http://alfalinux.sourceforge.net/mrename.php3 AUTHOR
