#!/usr/bin/ksh Command Interpreter in a sh script

Hi,

I have a developer that is trying to start a script with sh "scriptname". In the script, he is specifying #!/usr/bin/ksh as the command interpreter. For some reason sh is ignoring the #!/usr/bin/ksh. We are running Solaris 8. Does anyone have any ideas what could be causing this? Here is the script:

#!/usr/bin/ksh

#--create test file to read

#

echo "1" > test_file

echo "2" >> test_file

echo "3" >> test_file

#--WHILE READ should populate variables when shell contains #!/usr/bin/ksh

#

record_cnt=0

initial="OUTSIDE"

while read record ##--placed into $record

do

record_cnt=`expr $record_cnt + 1`

initial="INSIDE"

echo "Records Read=$record_cnt�

done < test_file ##--input file to be read

echo " "

echo "Records Read=$record_cnt"

echo "Initial=$initial"

exit 0

shells(4)							   File Formats 							 shells(4)

NAME

       shells - shell database

SYNOPSIS

       /etc/shells

DESCRIPTION

       The shells file contains a list of the shells on the system. Applications use this file to determine whether a shell is valid. See getuser-
       shell(3C). For each shell a single line should be present, consisting of the shell's path, relative to root.

       A hash mark (#) indicates the beginning of a comment; subsequent characters up to the end of the line are not interpreted by  the  routines
       which search the file. Blank lines are also ignored.

       The  following  default	shells are used by utilities: /bin/bash, /bin/csh, /bin/jsh, /bin/ksh, /bin/pfcsh, /bin/pfksh, /bin/pfsh, /bin/sh,
       /bin/tcsh,  /bin/zsh,  /sbin/jsh,  /sbin/sh,  /usr/bin/bash,  /usr/bin/csh,  /usr/bin/jsh,  /usr/bin/ksh,  /usr/bin/pfcsh,  /usr/bin/pfksh,
       /usr/bin/pfsh, and /usr/bin/sh, /usr/bin/tcsh, /usr/bin/zsh. Note that /etc/shells overrides the default list.

       Invalid shells in /etc/shells may cause unexpected behavior (such as being unable to log in by way of ftp(1)).
