sending mail message to root from a script

[Ed Hon]

Within a shell script, how do I send a mail message to root? Thanks.

[Kofi ARTHIABAH · Accepted solution]

take your pick:

echo " your message in here ....." | mail root

or
some_command | mail root
or
cat - << EOM | mail root
This
that
and the other line
to
root
EOM

etc.

The easiest way: as from command line:
mailx -s subject root@boxname.domaniename < message/or/filename

Ed:

...and if you would like to foward other account's mail (such as generated during cron tasks) to root, create /.forward with the list of accounts (one-per-line) that should forward their mail to root.

You might also want to use aliases (another option to the /.forward file).
In this way, mail that is sent to root will be aliased to your account.

As opposed to checking the root mail on multiple servers, all servers send the root mail to your mailbox.
