Sometimes it is necessary to notify others or do something on their own at some time. for those who read emails every day, it is the safest to send emails, in Linux, it is easy to use the Linux at command with mail.

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

Linux at command:

1. better understand the emailtext, such as in email.txt.

2. then write a script, such as run. sh.

#! /Usr/bin/bash

Mail-s "Title here"-c Address_CC Address_To <email.txt

3. execute

At 0815am Jan 24

At>./run. sh

At> ^ D

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

However, some servers limit the use of the at command, so there is a stupid way to run. sh and then run directly. sh to go to the background.

Time here is an integer, which refers to the number of seconds. However, when the terminal does not enter a period of time on some servers, the user will automatically log out, and some actions such as pwd can be performed in the script from time to time, ls and so on to prevent this situation. the above is the method to regularly send emails using the Linux at command in the Linux operating system.
