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。
