使用 cronjobs 和 rpi 上的日志时出现权限被拒绝错误

大家见鬼去吧。

我正在运行 raspberry pi 3B+。我有一个运行脚本的 cronjob（似乎运行良好），但当我查看 syslog 时，我看到了错误，您可以在下面找到这些错误。

我真的不知道哪里出了问题，我想知道你们是否知道。我的邮件（cat /var/mail/pi）什么都没有显示。

我确实运行了 log2ram，看看这有什么区别。

我的 crontab 如下所示：

0 */4 * * * sh /home/pi/Projects/refresh-web-os.sh

它运行的脚本如下所示：

#!/bin/sh

sessionToken=$( ssh -i <<CREDENTIALS>> -o StrictHostKeyChecking=no -p <<PORT>> <<SSH_ADDRESS> cat /var/luna/preferences/devmode_enabled )

if [ -z "${sessionToken}" ]; then
  echo "sessionToken is empty"
  sessionToken=$(cat /tmp/webos_devmode_token_tv.txt)
else
  echo "saving session token in temporary file (/tmp/webos_devmode_token_tv.txt)"
  echo ${sessionToken} > /tmp/webos_devmode_token_tv.txt
fi

if [ -z "${sessionToken}" ]; then
  echo "Unable to get token" >&2
  exit 1
fi

checkSession=$(curl --max-time 3 -s "<<CURL_CALL>>")

echo $checkSession

并且 syslog( grep cron /var/log/syslog -B 5 -A 5) 如下所示：
