centos8(linux): nohup生成的日志切分

本文主要是介绍centos8(linux): nohup生成的日志切分，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

一，bash代码

[lhdop@blog tools]$ more splitlog.sh

#!/bin/bash
LOG_PATH=/data/store/back/logs/back.log
now_date=`date +%Y%m%d`
DEST_PATH=/data/store/back/logs/back${now_date}.log
echo "dest log path:$DEST_PATH";
cp -axv $LOG_PATH $DEST_PATH
cat /dev/null > $LOG_PATH

 [lhdop@blog tools]$ crontab -l
55 23 * * * /data/store/back/tools/splitlog.sh

二，测试效果:

[lhdop@blog logs]$ ll
total 16272
…
-rw-rw-r-- 1 lhdop lhdop 15392197 Feb 11 16:16 back202202.log 

[lhdop@blog tools]$ ./splitlog.sh
dest log path:/data/store/back/logs/back20220211.log
lines:169360
'/data/store/back/logs/back202202.log' -> '/data/store/back/logs/back20220211.log’

[lhdop@blog tools]$ ll ../logs
total 16272
…
-rw-rw-r-- 1 lhdop lhdop 15392197 Feb 11 16:16 back20220211.log
-rw-rw-r-- 1 lhdop lhdop        0 Feb 11 17:18 back202202.log

三，查看bash和linux的版本:

linux

[lhdop@blog tools]$ cat /etc/os-release
NAME="CentOS Linux"
VERSION="8 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="8"
PLATFORM_ID="platform:el8"
PRETTY_NAME="CentOS Linux 8 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:8"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"
 
CENTOS_MANTISBT_PROJECT="CentOS-8"
CENTOS_MANTISBT_PROJECT_VERSION="8"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION=“8"

bash

[lhdop@blog tools]$ bash --version
