This is a little bash script that rotate logs as when the file reach a specified limit.
#!/bin/bash # FILE TO MONITOR FILE="/log/network_monitor.log" touch ${FILE} MaxFileSize=4096 while true do sh network_monitor.sh >> ${FILE} # SIZE IN BYTES** file_size=`du -b ${FILE} | tr -s '\t' ' ' | cut -d' ' -f1` if [ ${file_size} -gt ${MaxFileSize} ];then timestamp=`date +%s` mv ${FILE} ${FILE}.$timestamp touch ${FILE} else exit fi done
