crudely, it can be done with something along the lines of :

if [ -e debug_log.old ]
then
cp debug_log.old debug_log.older
fi

cp debug.log debug_log.old

> debug.log

note:

the reason *not* to use move in this case is that if something has file open, it will continue writing to the .old file.

depending on how often entries are written to the log, you might loose a few when the existing file is cleared with the ">".

once the script works as desired, you can stick it in cron to run at whatever times / intervals desired.

Hi,

Using cron execute the below script according to your timing.

sample script
---------------

#!/usr/bin/ksh
for i in 1
do
cp log copy_1_`date +%Y%m%d%H%M%S`
cp log copy_2_`date +%Y%m%d%H%M%S`
>log
done

Please change the log destinations.

"#!/usr/bin/ksh
for i in 1
do
cp log copy_1_`date +%Y%m%d%H%M%S`
cp log copy_2_`date +%Y%m%d%H%M%S`
>log
done
"

uh...doesn't that give you two copies of the same log????

Hi,
use logrotate tool for this purpose. You can download the depot @
http://hpux.connect.org.uk/hppd/hpux/Sysadmin/logrotate-2.5/

This is very simple, u can play with it easily (and without writing lines of code).
