The safest thing to do is change process X, do not create a process Y.

Code:
date_current=`date +%m%d%y`
java -Xms512m -Xmx512m com.mainloader.databaseLoader S 12 F > file.log.$date1 fname="file.log.$date1"
mv $fname /path/to/new/${fname}

Otherwise you are stuck with a kludge-y kind of thing where you call lsof or fuser repeatedly until you see that the logfile is no long open. See the man page on your system

example:
Code:
lsof /path/to/file.log.$date1
while [[ $? -ne 0 ]]
do
       sleep 10
       lsof /path/to/file.log.$date1
done

This does a lot of pointless polling. If your system has inotify (Linux/GNU derivative) you can call inotify to see when a file is closed. Same polling problem though.

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
