wc -c counts 1 char more per line
Hi,
this might be a basic question...
why is that wc -c counts 1 more per line than what is there.
for example,
> cat dum1.txt
123
12
> wc -c dum1.txt
7 dum1.txt

Thanks,
Sameer.

Check the number of characters in your file
Code:
$cat -e file_name

wc -c showing that count.

There are 7 characters in dum1.txt. You are missing to take the newlines into account.

The "extra" character is the newline at the end of both lines: 5 printable characters ("123" and "12") plus 2 newlines = 7.

Visual example (the blue line is inserted by me and not part of the original output):
Code:
$ cat dum1.txt
123
12
$ wc -c dum1.txt
7 dum1.txt
$ xxd dum1.txt
          1 2  3\n  1 2 \n
0000000: 3132 330a 3132 0a                        123.12.

Code:
# od -c dum1.txt
0000000   1   2   3  \n   1   2  \n
0000007

123+n+12+n=7 Smilie
