Usage for fish shell

[BrunoGiubilei]

Im try to configure nav using fish shell wrap, but dont works. Have support to fish shell yet?

Step by step of my test:

1. Download the binary
2. Copy the binary to /usr/bin/
3. run
   nav --setup
4. copy the wrapper snippet function
5. Adapted the function for fish instructions

function nav
    if count $argv > /dev/null
        command nav $argv
        return
    end

    set -l dir (env NAV_WRAPPED=1 command nav)

    if test -n "$dir"; and test -d "$dir"
        cd "$dir"
    end
end

6. run nav pure command
   nav
7. Get this error
   env: 'command': No such file or directory env: use -[v]S to pass options in shebang lines
