Frinds.. this is my first post, will try to provide all details accurately and in the best format...

Final Output: Trying to query oracle db and list all tables created yesterday for particular db and email. If not tables created then email shouldn't send Currently using shell script to connect db, get outputfile from perl and email to user. It runs perfectly fine but sends email even there are no tables created.

Questions: 1. Want to only email user if any tables were created, if no table created then shell script shouldn't send any email?

2. In subroutine "putHeader" how to get db name dynamic as per login db, TEST db under subroutine is hardcoded which is not right?

3. any easier way to include send email part within perl only so as to have only 1 file? 

FILENAME: run_list_tables.ksh

#!/bin/ksh
d=`date +%Y%m%d`

log_dir=$HOME
output_file=log.list

list_tables -login /@testdb -outputFile $output_file

mailx -s "list report : $d" test@mail < $output_file
