linux实战(五)----压缩备份文件并删除原文件----实例解析

原checkSpace.sh代码如下:

#!/bin/bash

function GetDiskSpc   
{   
    if [ $# -ne 1 ]   
    then   
        return 1   
    fi   
  
    Folder="$1$"  
    DiskSpace=`df -k |grep $Folder |awk '{print $5}' |awk -F% '{print $1}'`
    echo $DiskSpace   
}  




function CheckDiskSpc   
{   
  
DiskSpace=`GetDiskSpc $1`   
  
echo "The system $Folder disk space is $DiskSpace%"  
  
  echo "The system $Folder disk space is $DiskSpace%"  >> space.txt
  
if [ $DiskSpace -gt 90 ]   
then   
{   
    echo "The usage of system disk($Folder) is larger than 90%"  
       echo "The usage of system disk($Folder) is larger than 90%"   >> space.txt
}   
else   
{   
    echo "The usage of system disk($Folder)  is normal"  
     echo "The usage of system disk($Folder)  is normal"   >> space.txt
}   
fi  
  
}  


CheckDiskSpc  /boot  




修改后的checkSpace.sh脚本如下:

#!/bin/bash

function GetDiskSpc   
{   
    if [ $# -ne 1 ]   
    then   
        return 1   
    fi   
  
    Folder="$1$"  
    DiskSpace=`df -k |grep $Folder |awk '{print $5}' |awk -F% '{print $1}'`
    echo $DiskSpace   
}  




function CheckDiskSpc   
{   
  
DiskSpace=`GetDiskSpc $1`   
  
echo "The system $Folder disk space is $DiskSpace%"  
  
  echo "The system $Folder disk space is $DiskSpace%"  >> space.txt
  
if [ $DiskSpace -gt 90 ]   
then   
{   
    echo "The usage of system disk($Folder) is larger than 90%"  
       echo "The usage of system disk($Folder) is larger than 90%"   >> space.txt
}   
else   
{   
    echo "The usage of system disk($Folder)  is normal"  
     echo "The usage of system disk($Folder)  is normal"   >> space.txt
}   
fi  
  
}  


CheckDiskSpc  /boot  


tar cvf  - /data/shell/space.txt  > /data/shell/space.tar

rm space.txt





运行后结果如下:



发现已经成功把space.txt打包并删除了txt。


解压后可看到结果文件。


当然这里的路径可以进行相应调整。
