运行 crontab 启动脚本困难

我有以下 crontab 作业要在重启时运行：

PATH=/snap/bin:/usr/bin
@reboot run_me_startup.sh >> $HOME/startup_run_log.txt 2>&1

我的 docker 安装已将文件放在 /snap/bin 中（因此我的 PATH 语句）。我的 run_me_startup.sh 脚本如下：

echo "Startup Script"
sleep 240
echo "Running..."
sudo service apache2 stop && sudo service nginx stop
sudo chown $(whoami):$(whoami) /var/run/docker.sock
/snap/bin/docker network create dbnet
/snap/bin/docker network create nginx_network
export aws_access_key_id="secret"
export aws_secret_access_key="secret"
cd $HOME/The6ix/The6ixDjango && pwd && /snap/bin/docker-compose -f docker-compose.prod.yml down --remove-orphans
{
{
rm -rf $HOME/The6ix/The6ixDjango && cd $HOME/The6ix && git clone https://[email protected]/cooneycw/The6ixDjango.git 
} ||
{
cd $HOME/The6ix && git clone https://[email protected]/cooneycw/The6ixDjango.git
}
}
ls
cp $HOME/database.env $HOME/The6ix/The6ixDjango/database.env

我插入了sleep 240，确保代码执行前docker服务已经启动，我的输出日志如下：

Startup Script
Failed to stop nginx.service: Unit nginx.service not loaded.

我不明白为什么我的 crontab 中的 PATH 语句会出现 docker: not found 错误。我应该担心日志底部的 /bin/sh 注释吗？我是否以某种方式触发了脚本运行两次？Linux 新手……感谢您的慷慨！

事实证明，我没有意识到我的日志是附加的（我以为每次都会重建）。所以我的 cron 作业实际上并没有找到我的脚本（因此有重复的项目）。

更重要的是，snap 是垃圾，并产生了许多我必须解决的问题（通过 apt 安装了 docker.io 版本），我的脚本现在可以正确执行。
