"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
