Script - Remove files older than 1 day from /root

A quick bash script that I wrote that does the following:

Checks to see if the user is root (good to do with all your scripts if you 'sudo')
finds all files older than 1 day (-ctime +1)
deletes the files
sends an email to 'root' with a small report of the deleted files

(the numb -3 is to calculate the number of files deleted - there are 3 header lines in the report)
(the statement in bold allows you to specify file formats to delete...*.csv in my case...)

rm -rf $RM_LOG
