Linux如何定时清空日志内容和删除日志文件

touch /home/mppay/auto-truncate-log.sh
chmod u+x auto-truncate-log.sh

vi auto-truncate-log.sh

#!/bin/sh
#可填写多个路径
workdir=("/home/mppay/apache-tomcat-7.0.73/logs" "/home/mppay/logs")
for wdir in ${workdir[@]}; do
  echo -e "filepath is ${wdir}"
  # .log 文件和包含 log 标记的 .txt文件，以及 catalina.out 文件
  find $wdir -regex "^.*\(\.log\|log.*\.txt\|catalina.out\)$" -type f -print -exec truncate -s 0 {} \;
  if [ $? -eq 0 ]; then
    echo -e `date`" truncate logs successfully! \n"
  else
    echo -e `date`" truncate logs failed! \n"
  fi
done

#!/bin/sh
#可填写多个路径
workdir=("/home/mppay/apache-tomcat-7.0.73/logs" "/home/mppay/logs")
for wdir in ${workdir[@]}; do
  echo -e "filepath is ${wdir}"
  # .log 文件和包含 log 标记的 .txt文件，以及 catalina.out 文件
  find $wdir -regex "^.*\(\.log\|log.*\.txt\|catalina.out\)$" -and -mtime +5 -type f -exec  rm  -rf  {} \;
  if [ $? -eq 0 ]; then
    echo -e `date`" delete logs successfully! \n"
  else
    echo -e `date`" delete logs failed! \n"
  fi

find 路径 -name "文件名" -type f -print -exec truncate -s 0 {} \;　　#清空文件内容

find 路径 -mtime +天数 -type f -name "文件名" -exec rm -rf {} ;　　　 #删除文件

crontab -e
