I use the
to send myself reminders.
job runs a
mail program (1.33
and feeds the body of the message to the mailer's standard input.
To send a one-line reminder, I use a one-line command like this:
at 0427 tuesday
echo "send summary to Tim today" | mail firstname.lastname@example.org
It sends mail at (in this case) 4:27 a.m. on the next Tuesday. The mail says:
"send summary to Tim today."
To send more than one line, you can use a temporary file:
...put message body in msgfile
at 0808 feb 28
mail email@example.com < msgfile
Combine the output of UNIX commands and text with
here document (8.18
mail -s "Hard-working people" tom << END
These employees are working late. They deserve a bonus:
That sends a message to tom
at 1:15 a.m. tonight.
(This mailer accepts a subject on the command
line with its -s
The output of the
command gives detailed information about logged-in users;
not all systems have it.)
Unless you understand
how to quote here-document text (45.26
the message shouldn't have anything but letters, numbers, commas, and periods.
If your system administrator has set up the
program, it's good for easy one-line reminders on particular days.
If your UNIX has personal
that can send periodic reminders every Tuesday,
every hour, or whatever: use the commands in items 1 or 2 above.
