在Debian系统上,您可以通过使用notify-send
命令来定制消息通知。以下是具体步骤和一些相关信息:
首先,确保您的系统上安装了notify-send
。如果没有安装,可以使用以下命令进行安装:
sudo apt install notify-send
notify-send
命令允许您发送带有自定义消息、图标和紧急程度的桌面通知。例如:
notify-send "Dinner ready!"
notify-send "Tip of the Day" "How about a nap?"
您还可以使用HTML标记来增强通知的视觉效果,例如加粗文本:
notify-send -u critical "Build failed!" "There were <b>123</b> errors. Click here to see the results: http://buildserver/latest"
如果您想要在特定时间发送通知,可以将notify-send
与at
命令结合使用。例如,要在当前时间5分钟后发送一个通知,可以这样做:
echo "notify-send 'Time to wake up!' 'Enough work for today.'" | at now + 5 minutes
为了方便使用,您可以创建一个自定义的Bash函数来发送通知。以下是一个简单的remind
函数的示例,您可以在~/.bashrc
文件中添加以下代码:
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
# 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
}
保存上述代码到一个文件中,例如~/bin/remind
,然后在终端中运行以下命令使其生效:
source ~/bin/remind
现在您可以使用remind
命令来发送定制的通知了。
请注意,这些方法主要适用于基于Debian的发行版,如Ubuntu、Linux Mint等。不同的桌面环境可能会有不同的通知机制和工具,例如KDE Plasma桌面环境可能会使用kdialog
或notify-osd
。如果您使用的是特定的桌面环境,可能需要查找该环境特定的通知定制方法。
