bug#33574: grep -c question

[Helen Grubner]

Dear Team

 

Can you tell me, why I see this with grep -c on a file with following
content?

 

$ cat file_13.txt

1

2

3

4

5

6

7

8

9

10

11

12

13

 

$ grep -c 1 file_13.txt

5

 

Should it not show 6? When search for value 2, it is correct.

 

$ grep -c 3 file_13.txt

2

 

 

$ file file_13.txt

file_13.txt: ASCII text

 

Thank you

Alexander Grubner
