Check space of directories and send email if it has reached threshold limit
Hi,

I need help in writing unix script for checking space of some directories on the system and also send an email when it reaches the threshold limit.

I have written the followng code;

Code:
 
#!/bin/ksh
ADMIN="me@somewhere.com"
# set alert level 80% is default
THRESHOLD=80
df | grep -E "Filesystem|tmpfs|cdrom" | awk '{ print $5 " " $1 }' | while read output;
do
  #echo $output
  usep=$(echo $output | awk '{ print $1}' | cut -d'%' -f1  )
  partition=$(echo $output | awk '{ print $2 }' )
  if [ $usep -ge $THRESHOLD ]; then
    echo "Running out of space \"$partition ($usep%)\" on $(hostname) as on $(date)" |
     mail -s "Alert: Almost out of disk space $usep" $ADMIN
  fi
done

When I run the above code I get the following error;

dspace.ksh[15]: Iused: bad number
