Redirect echo output in shell script to logfile

Question

I have a shell script with lots of echo in it  I would like to redirect the output to a logfile  I know there is the command call cmd  gt  logfile txt  or to do it in the file echo  xy   gt  logfile txt  but is it possible to simply set the filename in the script which then automatically writes all echo s to this file

I tried to manage using the below command. This will write the output in log file as well as print on console.

#!/bin/bash

# Log Location on Server.
LOG_LOCATION=/home/user/scripts/logs
exec > >(tee -i $LOG_LOCATION/MylogFile.log)
exec 2>&1

echo "Log Location should be: [ $LOG_LOCATION ]"

Please note: This is bash code so if you run it using sh it will through syntax error

You can add this line on top of your script      bin bash   redirect stdout stderr to a file exec  amp  gt  logfile txt   OR else to redirect only stdout use   exec  gt  logfile txt
