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](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="$1"
local COMMAND="$2"
local MESSAGE="$3"
local OP="$4"
shift 4
local WHEN="$@"
# Display help if no parameters or help command if [[ $COUNT -eq 0 ]]
if [[ "$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
# 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
# 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
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。
