[英]Using crontab in linux to display a message everytime you open terminal?
I want to display message in terminal: 我想在终端中显示消息:
"Welcome!" “欢迎!”
when someone opens the terminal 当有人打开终端时
To print a message when opening a terminal (or logging in via ssh) you should use the message of the day (/etc/motd). 要在打开终端(或通过ssh登录)时打印消息,应使用当天的消息(/ etc / motd)。
You could use cron to overwrite this file at specific times, and so users will see the current message when they log in: 您可以使用cron在特定时间覆盖此文件,因此用户登录时将看到当前消息:
00 1 * * * "/bin/echo 'Good morning' > /etc/motd"
00 12 * * * "/bin/echo 'Good afternoon' > /etc/motd"
00 17 * * * "/bin/echo 'Good evening' > /etc/motd"
