URL: https://github.com/apache/incubator-dolphinscheduler/issues/4985


   最好改为在父shell中export foo=bar，而不是直接将脚本的内容进行替换
   ```
   echo '----------TEST1-------------'
   echo 'test1: ${f_date}'  ${f_date}
   echo 'test2: $f_date' $f_date
   
   echo '----------TEST2-------------'
   f_date2=${f_date:0:4}-${f_date:4:2}-${f_date:6:2}
   echo $f_date2
   echo '----------TEST3-------------'
   f_date=${f_date:0:4}-${f_date:4:2}-${f_date:6:2}
   echo $f_date
   ```
