Seg Fault with Awesome-wm

[edisonhello]

As title. My awesome config about this part:

        -- Screenshot                                                                                                                                         
    awful.key({ }, "Print", function()                                         
                awful.util.spawn("maim '/home/edison/Pictures/Screenshots/" .. os.date("Screenshot %Y-%m-%d %H:%M:%S Fullscreen.png") .. "'") end),
    awful.key({ "Shift" }, "Print", function()                                 
                awful.util.spawn("maim -s '/home/edison/Pictures/Screenshots/" .. os.date("Screenshot %Y-%m-%d %H:%M:%S.png") .. "'") end),
    awful.key({ "Control" }, "Print", function()                                                                                                              
                awful.util.spawn("maim | xclip -selection clipboard -t image/png -i") end),
    awful.key({ "Shift", "Control" }, "Print", function() 
                awful.util.spawn("maim -s | xclip -selection clipboard -t image/png -i") end),

Above two line work while another two always cause seg fault. I tried change the key combination (like modkey + p) but the result still same.

Also, maim | xclip -selection clipboard -t image/png -i in terminal works fine.

Something definitely is wrong with pipe. Try wrapping execution in sh -c, like this: awful.util.spawn("sh -c 'maim | xclip -selection clipboard -t image/png -i'") end),

This issue has nothing to do about Awesome-wm. @naelstrof I think it should be closed.

Thanks!

I'm using like this:

       awful.key({}, "Print", function () 
            awful.spawn.with_shell("maim ~/Imagens/Screenshots/Screenshot_$(date +%Y%m%d)_$(date +%H%M%S).png", false) end,
            {description = "Print desktop", group = "Screenshot"}),

       awful.key({ modkey }, "Print", function ()
            awful.spawn.with_shell("maim -i $(xdotool getactivewindow) ~/Imagens/Screenshots/Screenshot_$(date +%Y%m%d)_$(date +%H%M%S).png", false) end,
            {description = "Print window", group = "Screenshot"}),

       awful.key({ "Shift" }, "Print", nil, function ()
            awful.spawn.with_shell("maim -s ~/Imagens/Screenshots/Screenshot_$(date +%Y%m%d)_$(date +%H%M%S).png", false) end,
            {description = "Print area", group = "Screenshot"}),

       awful.key({ "Control" }, "Print", nil, function ()
            awful.spawn.with_shell("maim -s | xclip -selection c -t image/png", false) end,
            {description = "Print area to clipboard", group = "Screenshot"}),`

[foxpy]

ye, spawn.with_shell definitely sounds like a cleaner solution.
