Linux下Shell脚本实战之监测磁盘空间

• 一、脚本目的及要求
• 二、脚本内容
• 三、运行脚本

一、脚本目的及要求

(1) 监控/home下每各个用户目录的占用磁盘大小
(2) 监控/var/log下前10名占用磁盘大小
(3) 输出的磁盘空间报告文件加上时间戳保存
(4) 该脚本名为disk_sh

二、脚本内容

#!/bin/bash

#File Name:disk.sh
#Version:V1.0

# Parameters for Script 
# 
CHECK_DIRECTORIES=" /var/log /home" #Directories to check 
# 
############## Main Script ################################# 
# 
DATE=$(date '+%m%d%y') #Date for report file 
# 
exec > disk_space_$DATE.rpt #Make report file STDOUT 
# 
echo "Top Ten Disk Space Usage" #Report header 
echo "for $CHECK_DIRECTORIES Directories" 
# 
for DIR_CHECK in $CHECK_DIRECTORIES #Loop to du directories 
do
 echo "" 
 echo "The $DIR_CHECK Directory:" #Directory header 
# 
# Create a listing of top ten disk space users in this dir 
 du -S $DIR_CHECK 2>/dev/null |
 sort -rn |
 sed '{11,$D; =}' |
 sed 'N; s/\\n/ /' |
 gawk '{printf $1 ":" "\\t" $2 "\\t" $3 "\\n"}'
# 
done #End of loop 
# 
exit

三、运行脚本
