In the operation of actual cases, many people will encounter such a dilemma, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

Sometimes you need to inform others or do something yourself at a certain time. For some people who read email every day, it is safest to send an email. This is easy to do under the Linux operating system using the Linux at command with mail.

The Linux at command can run a program at a certain time, while mail can send and copy the body of the message stored in a text on the command line.

The specific usage of the Linux at command to send mail on a regular basis:

1. Get the email text ready, for example, in email.txt

two。 Then write a script, such as run.sh

#! / usr/bin/bash

Mail-s "Title here"-c Address_CC Address_To

. / run.sh

At > ^ D

Run.sh can be executed in 8:15am, Jan 24.

However, some servers restrict the use of the at command, so there is another stupid way

Add "speep time" at the beginning of run.sh, then run run.sh directly, and then go to the background.

Time here is an integer, which means how many seconds.

However, some servers will make the user logout automatically when the terminal does not enter for a period of time, so you can make some actions such as pwd,ls in the script from time to time to prevent this situation.
