在Debian系統中,消息推送功能可以通過多種方式實現,以滿足不同用戶的需求。以下是一些常見的方法:
notify-send:這是一個簡單的命令行工具,用于發送桌面通知。首先,確保安裝了 libnotify-bin
:
sudo apt-get install libnotify-bin
然后,使用以下命令發送通知:
notify-send "標題" "消息內容"
remind 命令:這是一個簡單的bash腳本,用于在指定的時間發送通知。您可以將以下腳本保存為 /bin/remind
文件,并在您的 .bashrc
配置文件中添加函數,以便在登錄時加載它:
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"
}
保存上述代碼到一個文件中,例如 /bin/remind
,然后在終端中運行以下命令使其生效:
source /bin/remind
通過上述方法,您可以在Debian系統中實現自定義消息推送功能。選擇哪種方法取決于你的具體需求和環境。
