Hello! I need the following: execute some command and go to the next
command of the function only when the first command is finished.
What I have now:
awful.key({}, "XF86AudioMute",
function ()
awful.util.spawn("amixer set Master toggle")
update_volume(volume_widget)
end)
Thus "update_volume" takes place earlier, than "amixer set Master
toggle" finishes it's execution, and I do not get required result.
One guy suggested using popen:
function ()
local f = io.popen("amixer set Master toggle")
f:close()
update_volume(volume_widget)
end)
It works fine, but I wonder if there is a way to implement it without
pipes. Could you please help me? Thank you.
