DISK 监测剩余量

#!/bin/bash  
temp=0.0  
DISK_SIZE=0.0  
for i in {0..26}  
do  
    echo -e "dscn0$i Disk"  
    echo "剩余可用大小GB"  
    temp=`ssh dscn0$i df -m|grep hadoop | awk '$4~/^[0-9]/ {split($4,array,"[A-Z]");b+=array[1]} END {print b/1024}'`  
    DISK_SIZE=$(echo "$DISK_SIZE + $temp" | bc)  
  
    echo -e "总数 剩余 占比 目录"  
    ssh dscn0$i df -h | grep hadoop  | awk '{print$2, $4, $5, $6}'  
done  
echo -e "\033[32m 剩余总大小: $DISK_SIZE GB \033[0m"  
  

bash 样式

  
    PS1='\[\e[1;32m\]\u@\h\[\e[m\]:\[\e[1;34m\]\W\[\e[1;33m\]\$\[\e[m\] '  
  

抽取一天的日志到另一个日志文件

#!/bin/bash  
  
TIME_LINE=$(date +%Y%m%d%H%M%S)  
  
  
function getOne(){  
    # 设定变量  
    if [ -z $1 ];then  
        echo -e "\033[31m Error: log Name is Null  \033[0m"  
        echo -e "\033[32m Simple : ./readlogs.sh getOne xxx.log  \033[0m"  
        exit 1  
    fi  
    log=$1  
    s=`date -d yesterday +%F` #前一天  
    #s=$(date +%F) #今天  
    e=$(date +%F) #今天  
    # 根据条件获得开始和结束的行号  
    sl=`cat -n $log | grep $s | head -1 | sed 's/^[ \t]*//g' | cut -f 1`  
    el=`cat -n $log | grep $e | tail -1 | sed 's/^[ \t]*//g' | cut -f 1`  
    echo -e "\033[32m start Line $sl \033[0m"  
    echo -e "\033[32m end Line $el \033[0m"  
    # 获取结果并输出到 `date`.log 文件  
    sed -n "$sl,$el"'p' $log >> check_auto_$TIME_LINE.log  
}  
  
case $1 in  
  
"getOne")  
	getOne $2  
	;;  
*)  
	echo -e "\033[1m usage: \n \t  [getOne] \033[0m"  
	echo -e "\033[1m DESC: \n \t getOne : 获得一天内的文件日志，并且进行导出。 \033[0m"  
	exit 2 # Command to come out of the program with status 1  
	;;  
esac  
exit 0
