invoke ksh in SunOS 5.7
Hi I have the following in .kshrc file

set -o allexport
HOSTNAME=$(uname -n)
HISTSIZE=50
EDITOR=vi
ENV=$HOME/.kshrc
PATH=$HOME/bin:/usr/bin:/usr/local:/etc/bin/:/bin:/usr/local/bin:.
bind =complete
set +o allexport
clear

and I have the following in .profile

umask 077
MANPATH=$MANPATH:/usr/man:/usr/share/man:/usr/X11R6/man:/usr/local/man
#MANPATH=$MANPATH:/usr/local/lib/perl5/man
PS1="[muru:\w]"
alias mk="make -f demo_proc.mk build prob EXE=prob OBJS=prob.o"
alias ho="cd /store/store3/cse.pub/marty/cop6726"
#stty erase ^h
PATH=$PATH:/bin:/usr/local/bin:/usr/X11R6/bin:/usr/ucb:/usr/tools/magic-6.5/bin/
export PATH=/usr/local/j2sdk1.3/bin:.SERVLET.JAR:$PATH
alias d="dict"
LD_LIBRARY_PATH=/usr/X11R6/lib:/usr/openwin/lib:/usr/local/lib
#export PATH MANPATH PS1 LD_LIBRARY_PATH
TERM=ansi;export TERM
ENV=$HOME/.kshrc; export ENV

my default shell is /bin/bash that is displayed when I execute echo $SHELL

I go to ksh from my defaut shell and it displays the command promt as $ but when I execute echo $SHELL it still shows
/bin/bash.

cat /etc/shells shows the following
$ cat /etc/shells
/usr/bin/bash
/bin/tcsh
/bin/csh
/sbin/sh
/bin/sh
/bin/noshell
/usr/local/bin/bash
/bin/bash

Is it ok? I mean it should show /bin/ksh when u are in ksh right? or am I making a mistake?
Am I not in ksh? then why is the prompt in $ sign?

a few words of explanation would be greatly appreciated.

Thanks
Muru

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.
