在Debian系统上,您可以通过多种方式来定制消息通知设置。以下是一些常见的方法:
notify-send
命令发送桌面通知notify-send
是一个简单的命令行工具,用于在Debian系统上发送桌面通知。首先,您需要确保 notify-send
已经安装在您的系统上。如果没有安装,可以使用以下命令进行安装:
sudo apt install notify-send
安装完成后,您可以使用以下示例命令来发送通知:
发送一个简单的消息通知:
notify-send "Dinner ready!"
发送一个带有自定义图标的通知:
notify-send -u critical "Build failed!" "There were 123 errors. Click here to see the results: http://buildserver/latest"
remind
命令发送定时提醒remind
是一个简单的bash脚本,用于在指定的时间发送通知。您可以将以下脚本保存为 /bin/remind
文件,并在您的 .bashrc
配置文件中添加函数,以便在登录时加载它:
#!/bin/bash
function remind () {
local COUNT="$#"
local COMMAND="$1"
local MESSAGE="$1"
local OP="$2"
shift 2
local WHEN="$@"
# Display help if no parameters or help command
if [[ $COUNT -eq 0 || "$COMMAND" == "help" || "$COMMAND" == "--help" || "$COMMAND" == "-h" ]]; then
echo "COMMAND"
echo "remind <message> <time>"
echo "remind <command>"
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'
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="$WHEN"
elif [[ "$OP" == "at" ]]; then
local TIME="$WHEN"
fi
# Add the reminder using at command
echo "$COMMAND" | at "$TIME"
}
您可以通过修改 /etc/motd
文件来定制登录时显示的系统信息。例如,您可以编辑该文件以添加自定义的欢迎信息或系统状态:
sudo nano /etc/motd
at
命令安排通知at
命令允许您在指定的时间执行命令。您可以结合 notify-send
使用 at
命令来安排通知:
echo "notify-send 'Stop it and go home now?' 'Enough work for today.'" | at now
您还可以通过编写自定义脚本来扩展通知功能。例如,您可以创建一个脚本,该脚本根据系统事件发送不同类型的通知。
以上就是在Debian系统上定制消息通知设置的一些方法。您可以根据自己的需求选择合适的方法进行配置。
