Please suggest any idea to solve this error.

Answer 1

The likely problem is that $window_id is an empty value. That would produce the error message from xterm.

In a quick check, I have the output from wmctrl -lp as

$ wmctrl -lp                                                                    
0x00400023  0 1036         localhost.localdomain [!./bar] - vile           
0x00a0000a  0 3981   localhost.localdomain xclock xclock

but the output of the expression with xprop is 0x0400023 (a different number of leading zeros).

If I change the fragment

awk '{print $5}' | sed 's/,//' | sed 's/^0x/0x0/'

to

awk '{sub(",","",$5);printf("%#010x",$5);}'

it gives a usable result (for my machine: ymmv ).
