[Message part 1 (text/plain, inline)]

Hello,

Using wc command in Linux, we're getting an unexpected behaviour.

The next command is returning 5 chars:

$ echo "TEST" | wc -m

The same behaviour is returned using the following command:

$ echo "TEST" | wc -c

Put the text in a file doesn't change the result.

If we type,

$ echo "TEST" | wc -L
the result is 4.

What the hell is happening?

Thanks,

Francisco Tena.

Tha's correct, since the 'echo' is outputting 5 characters:
T, E, S, T, and newline.

See also the output from od.

  $ echo "TEST" | od -tx1 -c
  0000000  54  45  53  54  0a
            T   E   S   T  \n
