1 The log content is cleaned regularly

# mkdir Test
# cd Test/
# touch a{1..10}.log
# ls
a10.log  a1.log  a2.log  a3.log  a4.log  a5.log  a6.log  a7.log  a8.log  a9.log
# for i in `ls ~/Test`;do echo "${i}">$i;done
 The above is the environment , In this similar environment , Cooperate with the task plan *.log journal 

# find /root/Test/ -name *.log |awk '{print "echo >" $1}' |bash

nginx_log_path="/kingdee/nginxLog"

function logrotate_nginx_log(){
    

  if [ -d "${nginx_log_path}" ]; then

    cd ${nginx_log_path}

    cp error.log  cutlog/error-$(date -d "today" +"%Y%m%d").log
    echo > error.log

    cp access.log cutlog/access-$(date -d "today" +"%Y%m%d").log
    echo > access.log

    find ${nginx_log_path}/cutlog -mtime +7 -type  f -name "*.log" -exec  rm -f  {
    }  \;
  fi
}
