This my frustrating disk space script that is supposed to send me a email whenever the disk space reaches 90% but this has some problem that just would not work ..can anyone please tell me when im going wrong
#!/bin/ksh
sendemail=-1
space=`df -bhk /users/siebelserver |awk '{print$5}'`
echo "$space is the file size percent"
#the statements below did not work, they are supposed to truncate the' % '
#capacity=${space%?}
#capacity=$space|/usr/xpg4/bin/awk -F"[%]" '{ print $1}'
capacity=`$space|sed s/.$//`
echo "capacity is $capacity "
if [ $capacity > 90 ]; then
echo "alert space getting full in $HOSTNAME "
sendemail=1
else
echo "enough space available"
fi
echo $sendemail
if [[ $sendemail > 0 ]]
then
/usr/bin/mailx -s "ALERT: Problem with file space on $HOSTNAME" "vqs@pgou
p.com"
fi
can anyone tellme where im making a mistake..
