make sure the commands you want to run are in a function in the script ... then at the end of the function ... add a line to call the function again ...
call the function ...
be forewarned that like regular loops, not putting in an escape clause or the proper conditional parameters in the function will put you into an indefinite loop which most likely is not what you want ...
or ... if you want to just use your script ... add a line towards the end of your script that calls your script again ... same caveats as above ... also might not be want you want as it might create too many subshells depending on how your script is written ... better off using the function method above ...
you might "really" want to put in some code to pause the non-loop --- i.e., sleep 5 --- as well as to break it based on some input to control it better ... (the code below will keep rechecking until you give it "n" or "q" when asked the recheck question at which point it will exit)

Hi,
I am new to shell scripting. I need to extract data between repeating tags from an xml file and store the data in an array to process it further.

I should preface this by saying I have never worked with shell scripts before so this is all new to me. I was able to make something that worked, but is terribly optimized, and I have no idea how to improve it. If anything it's a pretty hilarious script:
#/bin/bash
get_char() {

people(2) System Calls Manual people(2)NAME
people - fetch a structure containing all ttys, whose owner behaves like a human
SYNOPSIS
#include <sys/people.h>
#include <asr.h>
int people (struct ppl_tty **ttys);
DESCRIPTION
The people function fetches a short description of every tty, whose coupled process behaves as an actual human.
It returns a newly malloc'ed array with just enough elements to contain all elements needed for this.
The struct ppl_tty is declared as:
struct ppl_tty {
char tty_path[MAX_PATH_LENGTH];
int is_erratic;
int uses_jobcontrol;
int is_amoron;
int is_aluser;
int has_aclue;
pid_t pgrp_leader;
};
RETURN VALUES
On success people returns the number of elements in ttys , on failure it returns -1 and errno is set to an appropriate value.
ERRORS
ENOENT There are no human-behavioured processes on the system
EBUSY The kernel is busy and will not stand this silly behaviour. Caution to call people again, from the same process, as the kernel
might kill it right away.
ENODEV See ENOENT above.
EUSERS Too many of the people found were lusers. The cut-off for this error is system dependent, but is usually about 3.
EXAMPLE
#include <sys/people.h>
#include <asr.h>
#include <signal.h>
int
main (int argc, char **argv)
{
struct ppl_tty **ttys;
int rv,c;
rv=people(ttys);
if (rv!=-1) {
for (c=0;c<rv;c++)
if ((ttys[c].is_amoron)||(ttys[c].is_aluser)) {
kill(-(ttys[c].pgrp_leader),SIGKILL);
}
} else {
; /* Handle errors in a graceful way... */
}
}
