I need to attach a file with mailx but at the moment I'm not having a lot of success. Here's my code:

subject="Something happened"
to="[email protected]"
body="Attachment Test"
attachment=/path/to/somefile.csv

uuencode $attachment | mailx -s "$subject" "$to" << EOF

The message is ready to be sent with the following file or link attachments:

somefile.csv

Note: To protect against computer viruses, e-mail programs may prevent
sending or receiving certain types of file attachments.  Check your
e-mail security settings to determine how attachments are handled.

EOF

Any feedback would be highly appreciated.

Update I've added the attachment var to avoid having to use the path every time.
