Gvim use wmctrl in ubuntu

Gvim use wmctrl in ubuntu Use the wmctrl tools cocould maximize the windows of gvim in ubuntu. but I find a small issue for that. here is the wrong script: [plain] if has ("win32") au GUIEnter * simalt ~ X else au GUIEnter * call MaximizeWindow () endif function! MaximizeWindow () silent! Wmctrl-r: ACTIVE:-B add, maximized_vert, maximized_horz endfunction You cocould see that between "," and "maximized_vert" on line 8, there is a blank. it's the reason why the script can't works. so I remove the blank and it woks fine. so strange, because this scripts works well on my mac mini.
