Sending multiple files as an attachment to a Unix mail command

I have one piece of code mentioned below where it sends two files as an attachment.

mailx  -s "$ms - $cdate $ctime" $ReportGroup < ${mailmsg} >/dev/null 2>&1

      

        
        
        
      

    

Here mailmsg contains some files. Now I am trying to send another file xyz.csv

in the above command. how can i do the same?

Thanks in advance.
