So where is this PATH variable located?
These files are scripts. It's possible for PATH to be set in more than one location -- .bash_profile could add to the end of a PATH set by /etc/profile, for example.

So for setting global variable
I repeat, they're not global variables.

which means if i log in to 2 instances of putty and see the same path variable I need to modify ~/.bash_profile??? Is that correct???
I don't know why you'd expect to see two different PATHs when you logged in twice, but yes, you can put the changes you want into ~/.bash_profile.
Quote:
What about the .profile in my home directory?? How is that different??
.profile is what ksh uses, .bash_profile is what bash uses. Different local profiles for different shells make sense, otherwise you could end up with bash-specific commands causing ksh to throw up and ksh specific commands causing bash to throw up.

Again, these are script files, so it's possible for them to source other files too. Look at what's in them.

setusershell

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.
