I am trying to get the word count of a string using the wc command. But it gives me a different answer. It increases the number of words by 1.

This is the code:

echo Enter a string:

read str

len=`echo $str | wc -c`

echo you have entered: $str

echo and the word count: $len

The output is like this:

Enter a string:

robin

you have entered: robin

and word count: 6

What am I doing wrong? Please help me solve this. I will be very grateful. Thank you.
