Simple addition, help.

I add up the number of args that are not blank. It works, but the printout is a string that just keep concatenating on +1. So Ex. it goes through input of: bob toto " " tom ...I get 0+1+1+1, when all I want is 3. Any help is appreciated.

Code:
count=0

for name in $*
do

  if [ "$name" != "" ]; then
  count="$count+1"
  fi

done

echo $count

posix_getpwnam - Return info about a user by username

SYNOPSIS
array posix_getpwnam (string $username) DESCRIPTION
Returns an array of information about the given user. PARAMETERS
o $username - An alphanumeric username. RETURN VALUES
On success an array with the following elements is returned, else FALSE is returned: The user information array +--------+---------------------------------------------------+ |Element | | | | | | | Description | | | | +--------+---------------------------------------------------+ | name | | | | | | | The name element contains the username of the | | | user. This is a short, usually less than 16 char- | | | acter "handle" of the user, not the real, full | | | name. This should be the same as the $username | | | parameter used when calling the function, and | | | hence redundant. | | | | |passwd | | | | | | | The passwd element contains the user's password | | | in an encrypted format. Often, for example on a | | | system employing "shadow" passwords, an asterisk | | | is returned instead. | | | | | uid | | | | | | | User ID of the user in numeric form. | | | | | gid | | | | | | | The group ID of the user. Use the function | | | posix_getgrgid(3) to resolve the group name and a | | | list of its members. | | | | | gecos | | | | | | | GECOS is an obsolete term that refers to the | | | finger information field on a Honeywell batch | | | processing system. The field, however, lives on, | | | and its contents have been formalized by POSIX. | | | The field contains a comma separated list con- | | | taining the user's full name, office phone, | | | office number, and home phone number. On most | | | systems, only the user's full name is available. | | | | | dir | | | | | | | This element contains the absolute path to the | | | home directory of the user. | | | | | shell | | | | | | | The shell element contains the absolute path to | | | the executable of the user's default shell. | | | | +--------+---------------------------------------------------+ EXAMPLES
Example #1 Example use of posix_getpwnam(3) <?php $userinfo = posix_getpwnam("tom"); print_r($userinfo); ?> The above example will output something similar to: Array ( [name] => tom [passwd] => x [uid] => 10000 [gid] => 42 [gecos] => "tom,,," [dir] => "/home/tom" [shell] => "/bin/bash" ) SEE ALSO
