You could use the special command: "exec" to redirect stdout and stderr, e.g. if you put this at the top of your script ....

exec > /tmp/logfile$$ 2>&1

... all messages will go to the log file.

From man ksh...

Quote:

exec [arg ...]
Parameter assignments remain in effect after the command completes. If arg is given, the command specified by the arguments is executed in place of this shell without creating a new process. Input/output arguments can appear and affect the current process. If no arguments are given, the effect of this command is to modify file descriptors as prescribed by the input/output redirection list. In this case, any file descriptor numbers greater than 2 opened with this mechanism are closed when invoking another program.
