如何读取多个文件

如何读取多个文件并仅提取某些行并将它们写入各自适当的文件中示例：

file1.txt - file1_output;
file2.txt - file2_output;
file3.txt - file3_output;
file4.txt - file4_output;
file5.txt - file5_output;

more *.log | cat 
cat *.log | tee file1.txt file2.txt

File1:

OUTPUT:
FILE1_OUTPUT: SEVERE line... from File1
FILE2_OUTPUT: SEVERE line... from File2
FILE3_OUTPUT: SEVERE line... from File3

***SEVERE 线始终处于不同的位置

答案1

我会使用awk如下：

awk 'FNR==1{ close(ofname); ofname="output_"FILENAME } 
  /^SEVERE/{ print >ofname }' infile*
