Programming for linux: xprop setting multiple fields of atom property on newest questions tagged linux – Stack Overflow

I searched internet and found examples with setting only one field of property:

xprop -id "$windowid" -f _NET_WM_STATE 32a -set _NET_WM_STATE _NET_WM_STATE_ABOVE

but how can I set multiple fields?
I tried:

xprop -id "$windowid" -f _NET_WM_STATE 32a -set _NET_WM_STATE '_NET_WM_STATE_ABOVE, _NET_WM_STATE_SKIP_TASKBAR'

and

xprop -id "$windowid" -f _NET_WM_STATE 32aa -set _NET_WM_STATE _NET_WM_STATE_ABOVE,_NET_WM_STATE_SKIP_TASKBAR

and many other variants with no luck.
Is it possible ?

Ok….

I wrote patch for xprop to fix this. It works, but don’t know is it really correct.
Thanks to @MichałGórny.
