Character count in UNIX!
Hi,
I am Beginner in writing shell scripting. I have tried to get the character count using wc command. But it is not giving the correct result.
Could any one please tell me the reason?

Code:
[norkadm /opt/norkom/rbs/scheduler/tmp]$ cat k.ksh
Shell scripting

The character count should be 15 but it is displaying as 16 when i use wc.
Code:
[norkadm /opt/norkom/rbs/scheduler/tmp]$ wc -c k.ksh
      16 k.ksh

The trailing carriage return - a \n or newline character - is number sixteen.

That character is created by the <return> key.

Hi,
Thanks for your quick reply.
So when we take a character count do we have to subtract 1 from the output given by wc -c command?

You can see the newline character that Jim mentioned when you run od on your file:
Code:
$ od -t c k.ksh
0000000   S   h   e   l   l       s   c   r   i   p   t   i   n   g  \n

Another option to count character for each line:
Code:
while read line
do
   echo "${#line}"
done < k.ksh

Yes, your inference is correct if you do not want to consider the newline character.

Code:

$ printf "%s" "$(<file)" | wc -c
