从Oracle到UNIX外壳脚本​​的Wild Card参数

Question

for file in ${l_file_path}/${l_file_name} 
do 
    if [ -f $file ] 
    then 
      perform some operation; 
    else 
     echo "No files to process" 
    fi   
done 

l_file_name - 此变量来自oracle参数，例如：oracle.*.txt。使用上面的代码，它不会读取该目录中的文件。

结果：

No files to process 

Answer 1

for file in `ls ${l_file_path}/${l_file_name}` 
do  
    if [ -f $file ] 
    then 
      perform some operation; 
    else 
     echo "No files to process" 
    fi   
done
