【求助】docker里面的crontab部分不执行,但日志里面显示执行了

jimy1

请大神帮忙指点下，先谢谢了。
定时了2个任务，第一个能正常执行，第二个不行，但日志显示都执行了。
crontab实现文件每3分钟拷贝一个文件到相应文件夹；然后应用程序每5分钟读取解析这个文件，把解析的每行数据插入MySQL数据库。
crontab -l:

1. */3 * * * * /tmp/cp_file.sh
   
2.         */5 * * * * /tmp/aiFileTrans -c /tmp/aiFileTrans.xml

通过导出执行过程，发现报错：cannot execute binary file
然后我把第二个任务写到一个脚本里面，加上了先执行环境变量：

1. !/bin/bash
   
2. . /etc/profile
   
3. . ~/.bash_profile
   
4. /tmp/aiFileTrans -c /tmp/aiFileTrans.xml

复制代码

还是不运行第二个crontab任务，请大神指点，先谢谢了

具体过程：把第二个任务改为如下后（导出执行过程）：

之后我把第二行（第二个任务）写到cp_file3.sh里面，加了运行权限：

cron是执行了的，只是你的脚本哪里有问题，顺带说一句 第一行'!/bin/bash' 少个#，不过也没啥影响，具体还要看/tmp/aiFileTrans这个脚本，不过你也没贴出来。
