This will capture the output of the command to the file replicate_list.dat which can then be emailed to whomever

[nasadmin@localhost ~]$ pwd

/home/nasadmin  <--- this is where your output file will reside after issuing the below command

[nasadmin@localhost ~]$ nas_replicate -list >>replicate_list.dat      <--- This is capturing the output

[nasadmin@localhost ~]$ cat replicate_list.dat <--- This is what MY command produced

Name                      Type       Local Mover               Interconnect         Celerra      Status

[nasadmin@localhost ~]$ mail -s "Replicate_list info" mister@abc.com < replicate_list.dat  <--- this should send it -s=subject

or use the undocumented -report report option

Thanks for the update. Is there any way to capture the output and re-direct to mail rather than sending as an attachment ?

just pipe into mail or Mail - see the Linux man page

yes, able to capture the content in mail rather than attachment. Thank you.
