Question

我正在尝试每15分钟使用cron运行一个shell脚本。一小时45分钟。但是由于一些模糊的原因，它总是在cron执行时产生空字符串，而在我使用终端./my_script.sh运行时它会产生预期的结果。我阅读了许多与这些问题相关的答案，但没有一个能解决我的问题。

代码：

 #!/bin/bash
 PATH=/bin:/home/mpadmin/bin:/opt/ant/bin:/opt/cc/bin:/opt/cvsconsole:/opt/cvsconsole:/opt/cvsconsole:/sbin:/usr/bin:/usr/lib/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/var/mp/95930/scripts:/var/mp/95930/opt/bin:/opt/prgs/dlc101c/bin:/opt/cvsconsole
    tail -n 1000000 conveyor2.log | grep -P 'curingresult OK' | sed 's/FT\ /FT/g' |awk '{print $5 $13}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/master_list.txt
    tail -n 1000000 registration.log | grep -P 'TirePresent: 8' | sed 's/GT\ /GT/g' |awk '{print $7 $15}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/TBM_list.txt

我的cron

# run 15 and 45 mins every hour, every day
15,47 * * * *   sh /var/mp/95910/log/update_master_list.sh

权限：

所有文件都具有所有用户的读写权限和执行权限

希望我已经给了所有相关的＆amp;必要的信息

您可能需要先更改为 / var / mp / 95910 / log / 目录...

#!/bin/bash
cd /var/mp/95910/log/
PATH=/bin:/home/mpadmin/bin:/opt/ant/bin:/opt/cc/bin:/opt/cvsconsole:/opt/cvsconsole:/opt/cvsconsole:/sbin:/usr/bin:/usr/lib/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/var/mp/95930/scripts:/var/mp/95930/opt/bin:/opt/prgs/dlc101c/bin:/opt/cvsconsole
tail -n 1000000 conveyor2.log | grep -P 'curingresult OK' | sed 's/FT\ /FT/g' |awk '{print $5 $13}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/master_list.txt
tail -n 1000000 registration.log | grep -P 'TirePresent: 8' | sed 's/GT\ /GT/g' |awk '{print $7 $15}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/TBM_list.txt

或明确指定文件路径

#!/bin/bash
PATH=/bin:/home/mpadmin/bin:/opt/ant/bin:/opt/cc/bin:/opt/cvsconsole:/opt/cvsconsole:/opt/cvsconsole:/sbin:/usr/bin:/usr/lib/qt-3.3/bin:/usr/local/bin:/usr/local/sbin:/usr/sbin:/var/mp/95930/scripts:/var/mp/95930/opt/bin:/opt/prgs/dlc101c/bin:/opt/cvsconsole
tail -n 1000000 /var/mp/95910/log/conveyor2.log | grep -P 'curingresult OK' | sed 's/FT\ /FT/g' |awk '{print $5 $13}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/master_list.txt
tail -n 1000000 /var/mp/95910/log/registration.log | grep -P 'TirePresent: 8' | sed 's/GT\ /GT/g' |awk '{print $7 $15}' |sed 's/\"//g' | uniq | sort -n |uniq > /var/www/html/95910/TBM_list.txt

Shell脚本在终端中运行良好，不会在crontab中产生预期的输出
