Linux and Unix are time consuming stuff. Best sleep over it and start fresh next morning with a clear head 
I had and still have sometimes the same thing, that I look hours for some complicated solution while there is an easy way and when I see it I hit my forehead
But that's what a superb forum like this here is good for

SLEEP(3) Linux Programmer's Manual SLEEP(3) NAME
sleep - Sleep for the specified number of seconds SYNOPSIS
#include <unistd.h> unsigned int sleep(unsigned int seconds); DESCRIPTION
sleep() makes the calling thread sleep until seconds seconds have elapsed or a signal arrives which is not ignored. RETURN VALUE
Zero if the requested time has elapsed, or the number of seconds left to sleep, if the call was interrupted by a signal handler. CONFORMING TO
POSIX.1-2001. BUGS
sleep() may be implemented using SIGALRM; mixing calls to alarm(2) and sleep() is a bad idea. Using longjmp(3) from a signal handler or modifying the handling of SIGALRM while sleeping will cause undefined results. SEE ALSO
alarm(2), nanosleep(2), signal(2), signal(7) COLOPHON
