this is a standard problem in all rdbms releases. The utl_file implementation cannot write without LF - no chance. But you can try to use a pipe instead of the outputfile and write a little program which read out the pipe, eliminate the LF and write into the right file. So you can avoid all problems with utl_file (max. line length, LF,...).

If you often need to process information out of the database, implement a "listener" for such kind of work which read a named unix pipe. Implement some functionality to process unix commands, write files and so on. Implement also a package in pl/sql to communicate with this listener. We have done it this way and it works very stable and fast, even the pipesrv/pipechld software is no longer needed - and we can restrict the commands which can be executed!.
