在多個(gè)文件中g(shù)rep，如何不顯示文件名

linlone

如果grep命令多個(gè)文件名，輸出中包含文件名：

1. 
   
2. $ cat A.txt
   
3. hello
   
4. world
   
5. 
   
6. $ cat B.txt
   
7. fuck
   
8. hello
   
9. you
   
10. 
    
11. $ grep hello A.txt
    
12. hello
    
13. 
    
14. $ grep hello A.txt B.txt
    
15. A.txt:hello
    
16. B.txt:hello
    

復(fù)制代碼

我期望是這樣，如何做到呢？

1. $ grep hello A.txt B.txt
   
2. hello
   
3. hello

grep -h ...

-h, --no-filename
              Suppress the prefixing of file names on output.  This is the default when there is only one file (or only standard input)  to
              search.

1. 
   
2. root@localhost:~# grep hello A.txt B.txt | awk -F: '{print $(NF)}'
   
3. hello
   
4. hello
   
5. root@localhost:~# grep -h hello A.txt B.txt
   
6. hello
   
7. hello
