1、tools目录文件结构

[root@www tools]# tree tools/

tools/

├── bin

│ ├── del_history_files

│

└── etc

├── del_history_files.cfg

2 directories, 2 files

2、删除历史文件脚本 del_history_files

[root@www tools]# more tools/bin/del_history_files

#!/bin/sh

# 删除指定目录下，文件时间早于指定时间节点的文件，时间粒度：小时

# 配置文件格式 ： 需清理的目录=小时数

#

#

# define restricted path

PATH="/bin:/usr/bin:/sbin:/usr/sbin"

# adirname - return absolute dirname of given file

adirname() { odir=`pwd`; cd `dirname $1`; pwd; cd "${odir}"; }

# ---------

# constants

# ---------

MYNAM=`basename "$0"`

MYDIR=`adirname "$0"`

MYCFG="${MYDIR}/../etc/${MYNAM}.cfg"

MYTMP="${MYDIR}/../tmp"

MYLCK="${MYTMP}/${MYNAM}.lock"

# perform some locking (as good as it gets in a shell)

[ -s "${MYLCK}" ] && kill -0 `cat "${MYLCK}"` 2>/dev/null &&

die "${MYNAM}: already running!"

echo "$$" > "${MYLCK}"

PATHS=(`cat ${MYCFG}`)

for PP in ${PATHS[@]}

do

APP_PATH=`echo ${PP} | awk -F'=' '{print $1}'`

N=`echo ${PP} | awk -F'=' '{print $2}'`

if [ -d ${APP_PATH} ] ; then

T=`/bin/date --date "${N} hours ago" "+%Y%m%d%H%M"`

TMP_FILE="/tmp/`echo ${PP} | md5sum | awk '{print $1}'`"

touch -t ${T} ${TMP_FILE}

find ${APP_PATH} ! -newer ${TMP_FILE} -type f -print0 | xargs -0 -n 100 rm -rf

find ${APP_PATH} -type d -empty -print0 | xargs -0 -n 100 rm -rf &> /dev/null

fi

done

rm -rf ${MYLCK}

3、删除历史文件脚本的配置文件 del_history_files.cfg

[root@www tools]# more tools/etc/del_history_files.cfg

#需清理的目录=小时数

/home/logs/nginx=720

/home/logs/varnish=720

4、crontab 执行即可

[root@www tools]# more /etc/crontab

SHELL=/bin/bash

PATH=/sbin:/bin:/usr/sbin:/usr/bin

MAILTO=root

HOME=/

#clear old logs

00 6 * * * root /home/tools/bin/del_history_files
