Print console logs of a shell script

I have a shell script like below. I want to save the console full logs to a file.

#!/bin/bash
#This script is to import tables from mysql to hdfs

source /home/$USER/source.sh

[ $# -ne 1 ] && { echo "Usage : $0 table ";exit 1; }

table=$1

TIMESTAMP=`date "+%Y-%m-%d"`
touch /home/$USER/logs/${TIMESTAMP}.success_log
touch /home/$USER/logs/${TIMESTAMP}.fail_log
success_logs=/home/$USER/logs/${TIMESTAMP}.success_log
failed_logs=/home/$USER/logs/${TIMESTAMP}.fail_log

#Function to get the status of the job creation
function log_status
{
status=$1
message=$2
if [ "$status" -ne 0 ]; then
echo "`date +\"%Y-%m-%d %H:%M:%S\"` [ERROR] $message [Status] $status : failed" | tee -a "${failed_logs}"
#echo "Please find the attached log file for more details"
exit 1
else
echo "`date +\"%Y-%m-%d %H:%M:%S\"` [INFO] $message [Status] $status : success" | tee -a "${success_logs}"
fi
}

`hive -e "create table test_1 as select * from db.test"`

g_STATUS=$?
log_status $g_STATUS "Table created ${table}"
echo "******************************************************************************"

When I run the script The logs show only whether the job is success or failed. How do I get the whole console logs saved to a file.

How do save the both status logs to one file and the console logs to another file

Leverage two file descriptors, pointing to two different files and then redirect the relevant logs to the desired file descriptors.

For example, put this after shebang:

exec 3>console.log
exec 4>status.log

Now, to send all console logs to console.log, do:

echo .... >&3

Similarly, for all status logs:

echo ... >&4

Change the file names to meet your need.
