test integer value - ksh
|

| Hi, I'm stuck on testing some integer values within a script that
checks filesystem usage.
Whatever I do, the -ge operator seems not to work. Driving me crazy,
just cant see where the problem is.
Need a clue!
This is the script I made so far:
#!/bin/ksh
mailout ()
{
echo $suj
}
_attnlimit=80
_alertlimit=90
SNE=$(uname -n)
_sysfilesystems="/ /usr /var /home /tmp"
for fs in $_sysfilesystems
do
echo size = $size
size=$(df $fs|grep $fs|awk '{ print $4; }'|sed -e 's/%//g')
if [[ $size -ge $attnlimit ]]
then
suj="ATTN: ${SNE}:$fs reached ${size}%"
mailout
fi
if [[ $size -ge $alertlimit ]]
then
suj="ALERT: ${SNE}:$fs reached ${size}% !!"
mailout
fi
done
Now this is the output, notice it echo's all values where it should
only pick up the 84% (/home):
HST root /util/sysbeh # ./dusage.sh
size =
ATTN: HST:/ reached 27%
ALERT: HST:/ reached 27% !!
size = 27
ATTN: HST:/usr reached 72%
ALERT: HST:/usr reached 72% !!
size = 72
ATTN: HST:/var reached 25%
ALERT: HST:/var reached 25% !!
size = 25
ATTN: HST:/home reached 84%
ALERT: HST:/home reached 84% !!
size = 84
ATTN: HST:/tmp reached 7%
ALERT: HST:/tmp reached 7% !!

I am afraid you define two variables _attnlimit and _alertlimit, but
use them as attnlimit and alertlimit!

################################### check this condition if [[ $size
-ge $attnlimit ]] also if [[ $size -ge $alertlimit ]] here
you have used wrong variable name $attnlimit and $alertlimit it should
be start with underscore( _ ) as you have defined it earlier.

Who's gonna shoot me.. I'll line up bravely.
Seriously, these things always happen to me (so simple, so stupid).
Have been fiddling with it for at least 30 minutes.
I've read somewhere that using underscores in variables is a good
habbit,
this for possible conflict with built-in shell vars. Sigh.
Ty.
