I am writing a shell script command which counts the characters typed.
I am using wc. My script is echo $1 | wc -c. The problem is that it is counting a +1 character. For example, if i type 'hello' it displays (6) characters typed but it should display (5). Any ideas on how I can solve this problem?

Depending on the shell you're using, you could do this:
$ var='hello'
$ echo ${#var}
5
This way you don't need to call an external program.

echo $1 | wc -L what this does is, it Prints the maximum line length. – hello world Oct 05 '13 at 00:01
