I changed it to
#!/bin/dash
since it might enhance performance.

I didn't the following changes, but the OP likely wants to apply those.
Since the OP only wants to shrink the width of an active window, the
above "h="-line can be removed ...

>wmctrl -i -r 0x$window -b remove,maximized_vert,maximized_horz
>wmctrl -i -r 0x$window -e 0,-1,-1,$w,$h

... and I guess replacing $h with -1 does the job for this line, if not
replacing $h with $win_h should work for the above line.
