Are you saying that your tail -f commands are ineffective? Is it that you actually need to put al of these into the background so that they are all running:-
Code:
tail -f /Top/Folder1/logfile.log >> file.log &
tail -f /Top/Folder2/logfile.log >> file.log &
tail -f /Top/Folder3/logfile.log >> file.log &
tail -f /Top/Folder4/logfile.log >> file.log &

What output are you getting in file.log and what's not?
