Can anyone point where I am going wrong ???

| I Placed korn shell script and placed in the .profile.
This shell is supposed to ask me to connnect to a different user ,If
yes input password then I will get connected ,if not I will be in my
account.
But the script skips without asking me Yes /No,thereby keeping it
connected to my account.
This script runs fine when I execute it outside .profile
There are 3 issues wrt this script.
1.It does not ask me whether to get connected or not when I place in
..profile?
2.I want to pass the password for that different user .I tried using
"expect" and "send".But the ksh shell says
logon_script.ksh[13]: expect: not found
logon_script.ksh[14]: send: not found
3.This script runs fine when I execute it outside .profile
Can anyone try where I am going wrong.
Code is here
#!/usr/bin/ksh
set -o emacs
who am i
WHO=`who am i | awk '{print $1}'`
print ${WHO}
echo "Do you want to get connected to USER1? (Y/N)"
read yorn
if [ "${yorn}" = "Y" -o "${yorn}" = "y" ]
then
print ${yorn}
echo -en "\033]2;USER1\007"
su - user1
set -o emacs
cd tws
else
echo "You are in the directory "
pwd
echo -en "\033]2;My Window\007"
fi

| If the script works fine when running in a normal ksh, then its gonna
be something like a PATH issue .. so make sure you set your PATH at the
top of your script or usr full paths to your commands.

nicetom786@yahoo.com wrote a long message, and Steve responded...
I was unable to pass the su command the password for the USER1 user,
but it did not skip the if statement on me when I used the .profile
shown below. Further down is my sample output. I suspect that you will
need to use an "expect" script instead to send the password as a
parameter.
SAMPLE SCRIPT
=============
#!/usr/bin/ksh
WHO=$(who am i | awk '{print $1}')
echo "\nYou are currently connected as user: ${WHO} "
echo "Do you want to get connected to USER1? (Y/N)"
read YORN
if test "${YORN}" = "Y" -o "${YORN}" = "y"
then
echo "Connecting to USER1..."
su - user1
else
echo "Connecting to $WHO..."
echo "You are in directory: $(pwd)"
fi
SAMPLE OUTPUT
=============
pts/1 login: steven
steven's Password:
****************************************

You are currently connected as user: steven
Do you want to get connected to USER1? (Y/N)
y
Connecting to USER1...
user1's Password:
Welcome to USER1!

| Thanks Steven.
The code worked after I removed commands at the automated login script
screen.
For the second part to pass password in the script ,I tried using
spawn,expect ,send but all the above ar not reconised in the korn
shell.
Also I am able to man(reference) any of these .
Can you give me some idea.

have you installed "expect" ? I thought you said the script worked when
you ran it in the shell ? so it didnt work really ?
You can get the expect rpm from the aixtoolbox

All I can tell you about "expect" is that it has its own coding syntax,
much like Korn Shell or Perl. You would have to take a look at sample
expect scripts or find more info on the net, because I have not seen
any man pages for the expect package.
We have an expect script we use at our help desk to log on to other
systems so that usernames and passwords are not required to be
remembered by or displayed to the help desk staff. I was not involved
in the creation of the script so cannot tell you how it works or how to
code yours properly.
Just Google for "expect script UNIX" and you probably will get some
examples or documentation.

Here try this
autoexpect
If you do not have man page
http://manpage.willempen.org/1/autoexpect
for others
http://manpage.willempen.org
Snippet from
$ cat /usr/share/doc/expect-5.43.0/README
Expect may be ftp'd as mel/div826/subject/expect/expect.tar.gz from
expect.nist.gov. (Yes, the URL is much shorter:
http://expect.nist.gov/expect.tar.Z) Request email delivery by mailing
to "library@cme.nist.gov". The contents of the message should be (no
subject line) "send pub/expect/expect.tar.Z".
Once you have retrieved the system, read the INSTALL file. The papers
mentioned above can be retrieved separately (from the same directories
listed above) as:
doc/seminal.ps.Z (USENIX '90 - Intro and Implementation)
doc/sysadm.ps.Z (LISA '90 - System Administration)
doc/scripts.ps.Z (Comp. Systems '91 - Overview of Scripts)
doc/regress.ps.Z (USENIX '92 - Testing)
doc/kibitz.ps.Z (SP&E '93 - Automating Multiple
Interactive Programs Simultaneously)
