Hi ,

Struck with one basic question.

Iam expecting word count of 4 where "wc" is showing as 5 .

Code:
# echo "abcd" | wc
1 1 5

# echo abcd | wc
1 1 5

Code:
harsh@harsh-desktop:~$ echo "abcd" | od -bc
0000000 141 142 143 144 012
          a   b   c   d  \n

As you can see echo adds a newline at the end of the string echoed so you get 5 as the number of characters

Quoted or not quoted.. newline is added to the end of the string.

I changed my post about three times before I finally gave up and deleted it Smilie

It's the newline character. That's why there are 5.

Without the newline...
Code:
$ printf abcd | wc
       0       1       4
