"sed" to check file size & echo " " to destination file

Hi,

I've modified the syslogd source to include a thread that will keep track of a timer(or a timer thread). My intention is to check the file size of /var/log/messages in every one minute & if the size is more than 128KB, do a echo " " > /var/log/messages, so that the file size will be set back to zero.
If somebody can help me with a sed command to check the size of messages & to do a echo "" > messages ,if the size is greater than 128KB, I'll really grateful.

Wishes
Jay

SCROLLKEEPER-REBUILDDB(8)				      System Manager's Manual					 SCROLLKEEPER-REBUILDDB(8)

NAME
scrollkeeper-rebuilddb - rebuild the scrollkeeper document catalog database SYNOPSIS
scrollkeeper-rebuilddb [-p path ] [-v] [-q] DESCRIPTION
This rebuilds the ScrollKeeper database from the original OMF metadata files and documents. Under normal situations, this tool is not nec- essary. It is useful however if the database becomes corrupt, which could be caused by interruption of ScrollKeeper during an update of the database. Errors and warnings are logged to /var/log/scrollkeeper.log. OPTIONS
-p path Use path as the ScrollKeeper database directory. -v Verbose. Show warnings and error messages in addition to logging them to /var/log/scrollkeeper.log. -q Run in quiet mode, suppressing output of all but the most serious warning and error messages to STDOUT. Note that most output to the log file will be unchanged. FILES
