Question : bash script email handling

How can bash shell script look into the file with
following format

login name: real name: bithdate

compare the bithdate with the system date and if they
match - sends the email to the relevant user at 1:00 a.m.
every day

I tried every possible search to get a hint without any result.
Thanks

Answer : bash script email handling

Tyr this:

#!/bin/bash
# send_bd_email.sh
#
# Assuming the birthdate format is: MMDD
#
CURDT=$(date +%m%d)
MSG1=/tmp/msg$$.tmp
while read line
do
  nm=$(echo $line| cut -d: -f2|cut -f1)
  bd=$(echo $line| cut -d: -f3)
  email=$(echo $line| cut -d: -f1)
  if test $CURDT -eq $bd
  then
  { echo "subject: Happy Birthday!"
    echo "$nm we wish you the best on your birthday!!"
  } >$MSG1
    mail -tw $email <$MSG1
  fi
done rm $MSG1
exit
