Name it for example: check_quota.sh, add +x permission, and run: check_quota.sh user_name (for example: check_quota.sh penn).
#!/bin/sh

USER=$1
LIMIT=250000

Q=`sudo -u ${USER} quota | tail -n1 | awk '{print $2}'`
if [ "${Q}" -gt "${LIMIT}" ]; then
   echo "User: ${USER}; quota exceeded" | mailx -s "quota exceeded" webadmin aa12erp aa13nbc
fi
