Hi,

 

Documentation on 'wc' says:

----------------------------------------------

wc -m, --chars
              print the character counts

----------------------------------------------

 

But here follows the output I get:

 

>echo toto | wc --chars
5

>echo five | wc --chars
5

>echo four | wc --chars
5

>echo f  | wc --chars
2

>echo "" | wc --chars
1

 

Why does 'wc' add one character ?

 

Thanks.
