so far i have come up with the following

Code:

TODAY=`date +%d/%m/%y`
CURTIME=`date +%H:%M:%S`
 
#go to that directory
cd /local/home/userid/logs
 
#check the file size
ls -ltr sw_warn.log > sw_warn_filesize.txt
export file_size=`awk -F" " '{ print $5 }' sw_warn_filesize.txt`
 
# if greater than 5000000, then create a directory and copy the file. 
if [[ $file_size > 5000000 ]]
then
today_dir=mkdir TODAY_CURTIME
cp sw_warn.log /local/home/userid/logs/today_dir
 
#Instead of deleting the file, how to null sw_warn.log file
???

#remove this file
rm sw_warn_filesize.txt
else 
exit 0
fi

-------------------------------------------

We don't know your system.
Are the files open by an application at the time of the log file maintenance slot?

[me] yes these files are open by the apps
(If so, don't delete them, null them!).
[me] how?

Please show sample directory lists of every directory listed.
[me] the directory path is /local/home/userid/logs. under logs directory, i have three files
sw_warn.log
sw_error.log
eaijava.log

What is the maximum growth rate of the files? This determines how often to check.

[me] - i don't know the growth rate. btw, how to scheudle the shell script which keep checking the file size and run the script

Are there any disc space issues?
[me] no disc space issue.

SCANLOGS(8)						    InterNetNews Documentation						       SCANLOGS(8)

NAME

       scanlogs - Summarize and rotate INN log files

SYNOPSIS

       scanlogs [norotate]

DESCRIPTION

       scanlogs summarizes the information recorded in the INN log files which reside in the pathlog directory set in inn.conf (see newslog(5) for
       further details about these log files).	It is normally invoked by the news.daily(8) script which performs daily server maintenance tasks.

       It invokes "ctlinnd flushlogs" to close the news and error log files, rename them to add ".old" to the file names and open fresh news and
       error logs; the active file is also flushed to disk, along with the history database.

       By default, scanlogs rotates and cleans out the logs.  It keeps up to logcycles old compressed log files in pathlog/OLD (the logcycles
       parameter can be set in inn.conf).   scanlogs also keeps archives of the active file in this directory.

       It invokes tally.control if newgroup.log or rmgroup.log exists in pathlog (see the control.log entry of newslog(5) for more information
       about that).

       scanlogs displays the contents of errlog and news.crit, if non-empty, and runs innreport to summarize the contents of news and news.notice,
       and to update the unwanted.log file amongst other things (see more information about that in innreport(8)).

OPTIONS

       Only one option is currently accepted:

       norotate
	   Using this option disables the rotating and cleaning aspect of the log processing:  the logs files are only scanned for information and
	   no contents are altered.  If scanlogs is invoked more than once a day, the norotate option should be used to prevent premature log
	   cleaning.

FILES

       See newslog(5) for the list of log files processed by scanlogs.
