logroll.sh

# Add this script to root's cron
# Do it every sunday.
# 0 0 * * 0 /path/to/logroll.sh
function roll_log {
    if [ $(ls -s $1 | cut -d' ' -f1) -gt '10240' ]; then
        ts=$(date +%s)
        mv $1 ${1}.$ts
        if [ $? -ne 0 ];then
            exit 1
        fi
        touch $1
        tar cjf ${1}.${ts}.tar.bz2 ${1}.$ts
        rm ${1}.$ts  
    fi
}
