Is it because I am manually executing the script? Will it be fixed if I run that script in a crontab? or am I doing something wrong?
Hi.

That's what it's supposed to do.

Code:
tee Command

Purpose
       Displays the output of a program and copies it into a file.

If you only want the output in a file use

Code:
echo "Some Warning" >> $LOGFILE

instead.

If left like this, in a cronjob, you will get the output in your mailbox.
