I think "alarm" should be "alarm.sh", like this...
out=`awk '(NR>1) {print $9;exit}' alarm.sh`

6 --->o/p

request you to please let me for such behavior. as why i am not getting the o/p
i feel, it just executes the "echo $a"

ok, one question... whats there in that alarm.sh?
i feel
Code:
`awk '(NR>1) {print $9;exit}' alarm.sh`

this code is checking if the file alarm.sh is having more than one line or not. if its having more than one line, it prints out the $9(10th field on that file). if alarm.sh is empty, then the awk just exits.

alarm

ALARM(2)						     Linux Programmer's Manual							  ALARM(2)

NAME

       alarm - set an alarm clock for delivery of a signal

SYNOPSIS

       #include <unistd.h>

       unsigned int alarm(unsigned int seconds);

DESCRIPTION

       alarm arranges for a SIGALRM signal to be delivered to the process in seconds seconds.

       If seconds is zero, no new alarm is scheduled.

       In any event any previously set alarm is cancelled.

RETURN VALUE

       alarm  returns the number of seconds remaining until any previously scheduled alarm was due to be delivered, or zero if there was no previ-
       ously scheduled alarm.

NOTES

       alarm and setitimer share the same timer; calls to one will interfere with use of the other.

       sleep() may be implemented using SIGALRM; mixing calls to alarm() and sleep() is a bad idea.

       Scheduling delays can, as ever, cause the execution of the process to be delayed by an arbitrary amount of time.

       SVr4, SVID, POSIX, X/OPEN, BSD 4.3
