Add lrfs in PATH and make it executable.
Modify config.h:
- define a new function:
static const char *lrfs[] = { "lrfs", NULL };
- and replace the existing quit behavior by modifying its key binding with:
{ MODKEY|ShiftMask, XK_q, spawn, {.v = lrfs } },
To eliminate the compile time warning, comment out the function void quit(const Arg *arg)
in dwm.c.
