hi,
I am sending you a patch to solve a 'problem' at the wc program.
When used with -l option (to count the number of lines) the last
line isn't counted.
First of all, I do not know if it is really a bug, because a
newline must end with a '\n' char. But assume a file, that the
last line does not end with a '\n', so the last line does not
exist ?!
Summarizing:
The problem is: if the input does not end with a newline "\n",
this line is not counted. The classic example:
$ echo -n 'Test line' | wc -l
0
This patch below solve the problem.
PS: coreutils-5.0
