compton-trans [-w WINDOW_ID] [-n WINDOW_NAME] [-c] [-s] OPACITY

compton-trans is a bash script that sets _NET_WM_WINDOW_OPACITY attribute of a window using standard X11 command-line utilities, including xprop(1) and xwininfo(1). It is similar to transset(1) or transset-df(1).

-w WINDOW_ID

Specify the window id of the target window.

-n WINDOW_NAME

Specify and try to match a window name.

-c

Specify the currently active window as target. Only works if EWMH _NET_ACTIVE_WINDOW property exists on root window.

-s

Select target window with mouse cursor. This is the default if no window has been specified.

-o OPACITY

Specify the new opacity value for the window. This value can be anywhere from 1-100. If it is prefixed with a plus or minus (+/-), this will increment or decrement from the target window’s current opacity instead.

•Set the opacity of the window with specific window ID to 75%: 

compton-trans -w "$WINDOWID" 75

•Set the opacity of the window with the name "urxvt" to 75%: 

compton-trans -n "urxvt" 75
