需求：收集系统日期前一天的日志，归集到统一目录下，并需要有模块名称和ip标识；

#!/bin/bash
echo "===log backup start==="
#判断执行用户，为hps用户
if [ $(whoami) !=  hps ]
then
    echo "execute  user must be [hps]!"
    exit 2
fi

#注意月末最后一天日志会在下一个月目录下
ip=`ifconfig | grep inet | head -1 | awk '{print $2}'`
month1=`date +'%Y%m'`
day1=`date +'%Y%m'%d'`
day2=`date -d  "1 day ago" +'%Y%m'%d'`
day3=`date -d yesterday +%F`
backupDir=/tmp/$ip/$month1/$day2
mkdir -p $backupDir
cd   /home/hps/logs
if [  -d  /home/hps/logs/history ];then
        find  /home/hps/logs/history  -name  "*log*" -type f | grep  $day3 | xargs -I {}  tar  -czf {}.api.$ip.tar.gz
       find  /home/hps/logs/history  -name  "*gz*" | grep  $day3  | xargs -I {}  mv {} $backupDir
fi
echo  "===log backup end==="
