I can't conceive an occasion where wait or sleep would be preferable over cron for the purpose of (your words) "i want that this script will run automatic every 30 minutes ". Sounds more like lack of knowledge what cron does or artificial (superficial) restriction on the tools employed (aka: "do my homework assignment for me").
Anyway, if you insist on using sleep, "man sleep" tells you:
...
Syntax
sleep Seconds
...
hence, your script:
Code:
while : ; do
... your code ...
sleep 1800
done
Hope this helps - and if it doesn't i don't know how anything else will do.

sleep
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
