More generally, count any number of bytes from any source with "wc -c" (but for this it would count the line feed, too, so I echo without linefeed):
echo "$name\c" | wc -c | read name_len
That will not work for most people:
Also, for most people, name_len will not contain the result you want. In most shells, all elements of a pipeline are executed in a subshell.
Use command substitution instead:
Or better, as others have already pointed out, use the shell's own length expansion:
