Don't suppose you could show what you've tried so far? Or this is simply a demand for code? Not even a please?

<sigh>....just this once, then.

Code:

#!/bin/bash
CURRENT=$(df / | grep / | awk .{ print $5}. | sed .s/%//g.)
THRESHOLD=90

if [ "$CURRENT" -gt "$THRESHOLD" ] ; then
mail -s "Disk Space Alert" you@mail.com << EOF
Your root partition remaining free space is critically low. Used: $CURRENT%
EOF
fi

Hi dhirendrs,

Depending on your hard drive/parition/volume groups setup/configuration you may have to change the command slightly, more specifically the "print$#" part of the command:

Quote:

print $5

to this:

Quote:

print $4

The print command is outputting part of the string which is returned by the grep of df, if your configuration is not standard (like mine as I use volumes groups) you will need to change the "print $#". You can test the command by running the following:

Quote:

df / | grep / | awk "{ print $5}" | sed "s/%//g"

This is what mine returns if I use the "print$5"

Quote:

[root@server ~]# df / | grep / | awk "{ print $5}" | sed "s/%//g"
/dev/mapper/VolGroup00-LogVol00
59514964 17205476 39237488 31 /

But if I switch it to "print$4" is outputs this:

Quote:

[root@server01 ~]# df / | grep / | awk '{ print $4}' | sed 's/%//g'
31

I found out how to do the above from this site Linux Journal.

If you need more help please post back!!
