[TriLUG] Over quota script

[Jon Carnes]

Try something like this:
  #! /bin/bash
  #
  # Check for users that are over quota.
  # Assume all user dirs are under /home
  # look for folks above 40000kb (quota)
  #
  # Walk the users data tree to find the directory totals
  cd /home
  du -k > /root/tmp/guber
  #
  # Setup the marker for over/under quota folks
  echo "40000   ###target###" > /root/tmp/guber2
  #
  # Isolate the users directory - toss away the subdir info
  for i in `dir /home`
  do 
    grep -w ./$i$ /root/tmp/guber >> /root/tmp/guber2
  done
  #
  # Sort the directories by size
  sort -n </root/tmp/guber2 >/root/tmp/guber3
  #
  # Throw away info on users less than or equal to quota
  LINE=`grep -n "###target###" /root/tmp/guber3 |cut -f1 -d:`
  LINE=$(( $LINE + 1 ))
  sed -n "$LINE,$ p" /root/tmp/guber3 > /root/tmp/guber4
  #
  # Stop if there are no users over quota
  CHK=`head -1 /root/tmp/guber4`xxx
  if [ "xxx" == "$CHK" ]; then 
    exit 0
  fi
  # 
  # Email list of abusers to mis at mydomain.com
  # then send out stock message to each abuser
  cat /root/tmp/guber4 |mail -s "Folks over quota" mis at mydomain.com
  for i in `cat /root/tmp/guber4 |cut -f2 -d/`
  do
    cat /root/overquota.txt |mail -s "U R over quota: server alpha" $i
  done

This is all from memory so it may not be 100%, still it should be a good
framework to start from.  I used something very like this at a former
employer.

Let me know if you have any questions are comments -- and yes I know it
could be made more efficient.  As I said, this is from memory...
