3. of space is >= 90%

#<hr />
#<hr />

1. set admin email so that you can get email

ADMIN="gareth.knowles@firstcaribbeanbank.com"

1. set alert level 90% is default

#ALERT=90
ALERT=50
df -P | grep -vE '^Filesystem|tmpfs|cdrom' | awk '{ print $5 " " $1 }' | while r
ead output;
do
#echo $output
usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1 )
partition=$(echo $output | awk '{ print $2 }' )
if $usep -ge $ALERT ; then
echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(da
te)" |
mail -s "Alert: Almost out of disk space $usep" $ADMIN
fi
done

This is line 17: if $usep -ge $ALERT ; then

What I am I missing here?

It's really hard to read your script the way the website has formatted it. I suggest you wrap it with the markup tags for code:
{code}your code here{code}

It looks like line 15 is not producing the result that you are expecting. I suggest you echo the result from line 15, before using $usep in line 17, to see what it contains...for example:

usep=$(echo $output | awk 
'{ print $1}' | cut -d
'%' -f1 ) echo $usep

I see you have already done this in other places for other intermediate values....

Brian Veale,

Thanks for the advice,

After adding the echo command as suggested - echo $usep - the below was the output received:

55
48
10
28
14
-
22
4
24
35
61

Which is exactly the output I am looking for but the IF/THEN portion of the script seemed to be having issues with data being derived by LINE 15.

The issue still appears to be at line 18.

I am receiving the below output with the echo of $usep included - see below:

55
48
10
28
14
-
./diskspace.sh18: -: more tokens expected
22
4
24
35
61

I am attaching the script for your convenience.

The below are the partitions I am running query on:

/dev/hd4 0.06 0.03 55% 2434 26% /
/dev/hd2 2.12 1.11 48% 30114 11% /usr

Try fixing your df line with this

df -P | grep -vE '^Filesystem|tmpfs|cdrom|^/proc'

Orphy,

That seemed to have resolved the error. Because /proc partition had no space parameters to query on I would assume - see below:

/proc - - - - - /proc

Now I will wait for the email to see if that portion works. But the script seems to be fine now.

Thanks much guys,

Gareth...
