The number of command line arguments is $#.  For example:

        % cat foo.sh
        #!/bin/sh
        echo $#

        % sh foo.sh
        0

        % sh foo.sh hello world
        2

        % sh foo.sh "hello world"
        1

The argv[] equivalent is $@.

        % cat foo2.sh
        #!/bin/sh

        for argument in $@ ;do
                echo $argument
        done

        % sh foo2.sh
        %

        % sh foo2.sh hello world
        hello
        world
        %

        % sh foo2.sh "hello world"
        hello world
        %

For more details about the "special variables" of sh, read the sh(1)
manpage.

        % man 1 sh
