**need help for killing a process through script**
Hello All,
i hope you are fine.
I need a little help from you people--
inside a script i want to kill a parent process by checking it with the child process..
here i am selecting the child process id in p_pid.
next--
here i am cheching the P_PID with the 3rd field of 'ps -af' and selecting the respective 2nd column which is the parent id.
now the problem is when i am echoing sleep_pid its showing two values .
first one is the valid one but the second value i cant understand y comming. Everytime the 2nd value changed, seems to be randomly generated.
i want sleep_pid to hold only 12545.
can you please help me to get rid of the second value?
many thanks in advance....
Neel....

fork
FORK(2) BSD System Calls Manual FORK(2)NAME
fork -- create a new process
SYNOPSIS
#include <sys/types.h>
#include <unistd.h>
pid_t
fork(void);
DESCRIPTION
Fork() causes creation of a new process. The new process (child process) is an exact copy of the calling process (parent process) except for
the following:
o The child process has a unique process ID.
o The child process has a different parent process ID (i.e., the process ID of the parent process).
o The child process has its own copy of the parent's descriptors. These descriptors reference the same underlying objects, so that,
for instance, file pointers in file objects are shared between the child and the parent, so that an lseek(2) on a descriptor in the
child process can affect a subsequent read or write by the parent. This descriptor copying is also used by the shell to establish
standard input and output for newly created processes as well as to set up pipes.
o The child processes resource utilizations are set to 0; see setrlimit(2).
RETURN VALUES
Upon successful completion, fork() returns a value of 0 to the child process and returns the process ID of the child process to the parent
process. Otherwise, a value of -1 is returned to the parent process, no child process is created, and the global variable errno is set to
indicate the error.
ERRORS
Fork() will fail and no child process will be created if:
[EAGAIN] The system-imposed limit on the total number of processes under execution would be exceeded. This limit is configuration-
dependent.
[EAGAIN] The system-imposed limit MAXUPRC (<sys/param.h>) on the total number of processes under execution by a single user would
be exceeded.
[ENOMEM] There is insufficient swap space for the new process.

A fork() function call appeared in Version 6 AT&T UNIX.
