Hammer & Screwdriver putting together a couple of unix commands
Code:
> sample="sample"
> echo $sample | tr -d "\n" | wc -c
6

I used the translate function (tr) telling it to delete new-line (-d "\n") that would normally be part of the variable in this instance. That new-line does the carriage-return and line-feed when you echo it.

If vino's method doesn't work for you because you're using Bourne Shell, you can also try:

Code:
expr "$string" : ".*"

or

Code:
echo "$string" | awk '{ print length }'
