写个定时切换壁纸的脚本

方案一：Linux (使用cron + Python)
方案二：Windows (PowerShell + 任务计划程序)
方案三：macOS (LaunchAgent)
使用说明
自定义配置

我来帮你写一个定时切换壁纸的脚本,这里提供几种方案的脚本，你可以根据你的操作系统选择。

Linux (使用cron + Python)

Python 脚本 (change_wallpaper.py)

设置定时任务 (Cron)

#!/bin/bash
# setup_cron.sh - 设置定时切换壁纸
# 1. 先给脚本添加执行权限
chmod +x change_wallpaper.py
# 2. 获取脚本的绝对路径
SCRIPT_PATH=$(realpath change_wallpaper.py)
# 3. 添加到crontab，设置每30分钟切换一次
(crontab -l 2>/dev/null; echo "*/30 * * * * /usr/bin/python3 $SCRIPT_PATH") | crontab -
echo "定时切换壁纸已设置完成！每30分钟切换一次"
echo "如需修改时间间隔，请编辑 crontab: crontab -e"

Windows (PowerShell + 任务计划程序)

PowerShell 脚本 (change_wallpaper.ps1)

创建Windows任务计划

# setup_windows_task.ps1 - 设置Windows定时任务
# 脚本路径
$scriptPath = "$PSScriptRoot\change_wallpaper.ps1"
$taskName = "WallpaperChanger"
# 创建基本任务
$action = New-ScheduledTaskAction -Execute "PowerShell.exe" `
    -Argument "-File `"$scriptPath`""
# 设置触发器 - 每30分钟执行一次

    -Trigger $trigger `
    -Settings $settings `
    -Description "每30分钟自动切换壁纸"
Write-Host "Windows定时切换壁纸已设置完成！"

macOS (LaunchAgent)

创建macOS脚本 (change_wallpaper.sh)

#!/bin/bash
# change_wallpaper.sh - macOS定时切换壁纸
# 壁纸目录（请修改为你的壁纸目录）
WALLPAPER_DIR="$HOME/Pictures/Wallpapers"
# 创建日志目录
LOG_DIR="$HOME/Library/Logs"
mkdir -p "$LOG_DIR"
# 获取随机壁纸
random_wallpaper() {
    local wallpapers=()
    # 收集支持的文件类型
    for ext in jpg jpeg png gif; do
        while IFS= read -r file; do
            wallpapers+=("$file")
        done < <(find "$WALLPAPER_DIR" -type f -name "*.$ext" 2>/dev/null)
    done
    # 随机选择
    if [ ${#wallpapers[@]} -gt 0 ]; then
        echo "${wallpapers[$RANDOM % ${#wallpapers[@]}]}"
    else
        echo ""
    fi
}
# 设置壁纸
set_wallpaper() {
    local wallpaper="$1"
    if [ ! -z "$wallpaper" ] && [ -f "$wallpaper" ]; then
        # 使用osascript设置壁纸
        osascript -e "tell application \"System Events\" to set picture of every desktop to \"$wallpaper\""
        echo "$(date): 成功切换壁纸: $wallpaper" >> "$LOG_DIR/wallpaper_changer.log"
    else
        echo "$(date): 未找到壁纸文件" >> "$LOG_DIR/wallpaper_changer.log"
    fi
}
# 主函数
main() {
    # 检查壁纸目录
    if [ ! -d "$WALLPAPER_DIR" ]; then
        mkdir -p "$WALLPAPER_DIR"
        echo "$(date): 壁纸目录不存在，已创建: $WALLPAPER_DIR" >> "$LOG_DIR/wallpaper_changer.log"
        exit 1
    fi
    # 获取并设置壁纸
    selected_wallpaper=$(random_wallpaper)
    set_wallpaper "$selected_wallpaper"
}
# 执行主函数
main

安装LaunchAgent

# 加载LaunchAgent
mkdir -p ~/Library/LaunchAgents
cp com.user.wallpaperchanger.plist ~/Library/LaunchAgents/
launchctl load ~/Library/LaunchAgents/com.user.wallpaperchanger.plist
# 如果修改了，可以重载
launchctl unload ~/Library/LaunchAgents/com.user.wallpaperchanger.plist
launchctl load ~/Library/LaunchAgents/com.user.wallpaperchanger.plist

使用说明

准备工作：创建一个壁纸目录，放入你喜欢的壁纸图片
选择脚本：根据你的操作系统选择对应的脚本
修改配置：将脚本中的壁纸目录路径更改为你的实际路径
设置定时：
- Linux: 运行setup_cron.sh
- Windows: 运行setup_windows_task.ps1
- macOS: 安装LaunchAgent
