删除大小为0的文件

find . -name "*" -type f -size 0c | xargs -n 1 rm -f

但是如果文件名有空格，则不能删除,但是可以将带空格的文件名改成没有空格，则就可以删除了。

命令如下：

for file in *;do mv "$file" "$(echo $file|tr -d ‘ ‘)";done

修改linux系统本地时间为东八区

cp -f /usr/share/zoneinfo/Asia/Shanghai /etc/localtime

设定后台进程：

crontab -e
00 00 * * * /bin/bash  /var/xxx.sh

设定nginx自动切割日志：

#!/bin/bash
# This script run at 00:00

# The Nginx logs path
logs_path="/var/log/nginx/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/
mv ${logs_path}localhost.access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/localhost.access_$(date -d "yesterday" +"%Y%m%d").log
#kill -USR1 `cat /var/run/nginx.pid`
killall –s USR1 nginx

查看nginx状态，参考http://wiki.nginx.org//NginxChsStubStatusModule?highlight=(status)
