一些建议

解决方案

 ＃！/斌/庆典
源/ etc / profile文件＃设备进行检查
DEVNAME =的/ dev / sdb1的令p =`DF -k $ DEVNAME | grep的-v ^文件| AWK'{printf的（％i的，$ 3 * 100 / $ 2）; }'`
如果[$ P -ge 90]
然后
  DF -h $ DEVNAME |邮件-s空间不足[e-mail]
科幻
 

crontab的这不论你想要一个警报运行

编辑：对于多盘

 ＃！/斌/庆典
源/ etc / profile文件＃设备检查
DEVNAMES =的/ dev / SDB1的/ dev / sda1的在$ DEVNAMES DEVNAME
做
  令p =`DF -k $ DEVNAME | grep的-v ^文件| AWK'{printf的（％i的，$ 3 * 100 / $ 2）; }'`
  如果[$ P -ge 90]

DONE
 

I bought a NAS box which has a cut down version of debian on it.

It ran out of space the other day and I did not realise. I am basically wanting to write a bash script that will alert me whenever the disk gets over 90% full.

Is anyone aware of a script that will do this or give me some advice on writing one?

解决方案

#!/bin/bash
source /etc/profile

# Device to check
devname="/dev/sdb1"

let p=`df -k $devname | grep -v ^File | awk '{printf ("%i",$3*100 / $2); }'`
if [ $p -ge 90 ]
then
  df -h $devname | mail -s "Low on space" [e-mail]
fi

Crontab this to run however often you want an alert

EDIT: For multiple disks

#!/bin/bash
source /etc/profile

# Devices to check
devnames="/dev/sdb1 /dev/sda1"

for devname in $devnames
do
  let p=`df -k $devname | grep -v ^File | awk '{printf ("%i",$3*100 / $2); }'`
  if [ $p -ge 90 ]
  then
    df -h $devname | mail -s "$devname is low on space" [e-mail]
  fi
done
