Thanks for your help.
Your method works to only only level of child process , what about if the child process has sub child process
see the following example :-
suppose, if we want to kill PID=1200, we would like to kill 1520 1544 1508

$ ps -ef
UID PID PPID TTY STIME COMMAND
Administ 820 1 0 22:48:31 /usr/bin/bash
Administ 860 820 0 22:48:35 /usr/bin/bash
Administ 1200 860 0 22:48:37 /usr/bin/bash
Administ 1520 1200 0 22:48:38 /usr/bin/bash
Administ 1544 1520 0 22:53:15 /usr/bin/bash
Administ 1508 1544 0 22:53:19 /usr/bin/ps

Child Process PID

Hi, Can anybody solve this query? A parent process forks 2 child processes. How does the child process know it's PID without the parent process sending it. Apart from the "ps-ef" option, what other options are there if any? (2 Replies)

getusershell

getusershell(3C)					   Standard C Library Functions 					  getusershell(3C)

NAME

       getusershell, setusershell, endusershell - get legal user shells

SYNOPSIS

       #include <unistd.h>

       char *getusershell(void);

       void setusershell(void);

       void endusershell(void);

DESCRIPTION

       The  getusershell()  function  returns  a  pointer  to  a  legal  user  shell  as defined by the system manager in the file /etc/shells. If
       /etc/shells does not exist, the following locations of the standard system shells are used in its place:

	 /bin/bash		    /bin/csh
	 /bin/jsh		    /bin/ksh
	 /bin/ksh93		    /bin/pfcsh
	 /bin/pfksh		    /bin/pfsh
	 /bin/sh		    /bin/tcsh
	 /bin/zsh		    /sbin/jsh
	 /sbin/pfsh		    /sbin/sh
	 /usr/bin/bash		    /usr/bin/csh
	 /usr/bin/jsh		    /usr/bin/ksh
	 /usr/bin/ksh93 	    /usr/bin/pfcsh
	 /usr/bin/pfksh 	    /usr/bin/pfsh
	 /usr/bin/sh		    /usr/bin/tcsh
	 /usr/bin/zsh		    /usr/sfw/bin/zsh
	 /usr/xpg4/bin/sh

       The getusershell() function opens the file /etc/shells, if it exists, and returns the next entry in the list of shells.

       The setusershell() function rewinds the file or the list.

       The endusershell() function closes the file, frees any memory used by getusershell() and setusershell(), and rewinds the file /etc/shells.

RETURN VALUES

       The getusershell() function returns a null pointer on EOF.

BUGS

       All information is contained in memory that may be freed with a call to endusershell(), so it must be copied if it is to be saved.

NOTES

       Restricted shells should not be listed in /etc/shells.
