在Debian系统中，有多种方法可以设置消息通知。以下是一些常见的方法：
notify-send 命令notify-send 是一个用于发送桌面通知的命令行工具。首先，你需要确保 notify-send 已经安装在你的系统上。在基于Debian的发行版上，可以使用以下命令安装：
sudo apt install notify-send 安装完成后，你可以使用 notify-send 命令来发送通知。例如：
notify-send "Dinner ready!" 你可以通过 man notify-send 命令查看更多选项，例如使用紧急程度、自定义图标等。
remind 命令remind 是一个简单的命令行工具，用于在指定的时间发送通知。首先，你需要将 remind 函数添加到你的 .bashrc 配置文件中：
echo ' function remind () { local COUNT"$#" local COMMAND="$1" local MESSAGE="$2" local OP="$3" shift 3 local WHEN="$@" # Display help if no parameters or help command if [[ COUNT -eq 0 "COMMAND" "help" "COMMAND" "--help" "COMMAND" "-h" ]]; then echo "COMMAND" echo "remind" echo "remind" echo echo "DESCRIPTION" echo "Displays notification at specified time" echo echo "EXAMPLES" echo 'remind "Hi there" now' echo 'remind "Time to wake up" in 5 minutes' echo 'remind "Dinner" in 1 hour' echo 'remind "Take a break" at noon' echo 'remind "Are you ready?" at 13:00' echo 'remind list' echo 'remind clear' echo 'remind help' echo return fi # Check presence of AT command if ! which at /dev/null; then echo "remind: AT utility is required but not installed on your system. Install it with your package manager of choice, for example 'sudo apt install at'." return fi # Run commands: list, clear if [[ COUNT -eq 1 ]]; then if [[ "COMMAND" "list" ]]; then at -l elif [[ "COMMAND" "clear" ]]; then at -r $(atq cut -f1) else echo "remind: unknown command COMMAND. Type 'remind' without any parameters to see syntax." fi return fi # Determine time of notification if [[ "OP" "in" ]]; then local TIME="$NOW" WHEN="$WHEN" elif [[ "OP" "at" ]]; then local TIME="$TI" fi # Schedule notification case "$OP" in in) # Add code to schedule notification in the future ;; at) # Add code to schedule notification at the specified time ;; *) echo "remind: unknown operation OP. Type 'remind' with -in or -at option." return ;; esac } ' >> ~/.bashrc source ~/.bashrc 然后，你可以使用 remind 命令来设置提醒：
remind "I'm still here" now remind "Time to wake up!" in 5 minutes remind "Dinner" in 1 hour remind "Take a break" at noon remind "It's Friday pints time!" at 17:00。
