I have wrote a command, that works in bash, but won't in fish.

var=$(dmenu_path | dmenu); exec $var

Subshells in fish are started with just brackets, without the $, also, you set variables with the set command, instead of using =, it would become:

set var (dmenu_path | dmenu); exec $var

I've allready try this.

~> set var (dmenu_path | dmenu); exec $var
fish: Variables may not be used as commands. Instead, define a function like 'function var; xterm $argv; end'. See the help section for the
function command by typing 'help function'.
set var (dmenu_path | dmenu); exec $var
                                   ^

Hm, if you can't pass variables to exec, that pretty much defeats trying to do this, maybe report this as a bug to fish ?
