Sorry for the short info Smilie : 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
