我在 Raspberry Pi Model 3B 上运行 Linux 9。
我定期通过 CRONTAB 启动一项任务,通过电子邮件发送 (/usr/bin/mail) 一些文件。工作中的任务和我得到的文件。但是,它还在附件的系统日志中记录二进制数据。这会导致 SYSLOG 变得非常大并且几乎无法使用。如何禁止将此日志记录到 SYSLOG?
编辑/更新 2022 年 8 月 21 日 以下是一位评论者要求的一些附加信息。
这是 CRONTAB 中的命令行:
0 0 * * * /usr/pgms/sendtome.sh "PiV2" "AcuritePgmLog.txt;todaydata.txt;rainfall3.txt;Acurite_error.log;" > /mnt/usbdrive/output/CRON_output.txt 2>&1
这是 sendtome.sh 脚本:
cat /usr/pgms/sendtome.sh
#!/bin/bash
MyPath="/mnt/usbdrive/output/"
TO="[email protected]"
MESSAGEx="Midnight `date '+%Y-%m-%d %H:%M:%S %Z'` $HOSTNAME Pi report"
echo $MESSAGEx
temp=$(echo $2 | tr ";" "\n")
for file in $temp
do
echo "> [$file]"
done
/usr/bin/mysql -uxyz -pzz -e "select * from pidata WHERE (Date_Reading > DATE_ADD((SELECT MAX(Date_Reading) FROM pidata), INTERVAL -3 HOUR))" acurite > /mnt/usbdrive/output/todaydata.txt
declare -a attargs
for att in $temp; do
x=$MyPath$att
echo $x
attargs+=( "-A" "$x" )
done
echo ${attargs[@]}
echo $MESSAGEx | /usr/bin/mail -s "$1" "$TO" ${attargs[@]}```
这是 CRON_output.txt 文件:
cat /mnt/usbdrive/output/CRON_output.txt
Midnight 2022-08-21 00:00:02 CEST PiV2 Pi report
> [AcuritePgmLog.txt]
> [todaydata.txt]
> [rainfall3.txt]
> [Acurite_error.log]
/mnt/usbdrive/output/AcuritePgmLog.txt
/mnt/usbdrive/output/todaydata.txt
/mnt/usbdrive/output/rainfall3.txt
/mnt/usbdrive/output/Acurite_error.log
-A /mnt/usbdrive/output/AcuritePgmLog.txt -A /mnt/usbdrive/output /todaydata.txt -A /mnt/usbdrive/output/rainfall3.txt -A /mnt/usbdrive/output/Acurite_error.log
最后,这是昨晚 Pi 上的系统日志文件的摘录。之前的几行与下面第一行的内容类似:

我希望这有助于解释这种情况。哦,是的,这是 SSMTP.conf 文件
cat /etc/ssmtp/ssmtp.conf

# Make this empty to disable rewriting.
