Pity on me 4 a repost...

I'm going to spend some points to re-ask this question, which teaches me a lesson:  Don't grade a question without testing the answer *thoroughly* first.

Having said that, here's the question (which I've asked here before) again.  I'm running a CGI script that I can't get to work.  This is the script:

#!/bin/sh
PATH=$PATH:/usr/bin#

# ^ the above line was added as a result of the last question...

echo "Content-type: text/html"
echo
echo "<HTML><HEAD>"
echo "<TITLE>Is Laura There?</TITLE>"
echo"</HEAD><BODY>"

ison='who | grep lemay'

if [ ! -z "$ison" ]; then
      echo "Laura is logged in"
else
      echo "Laura isn't logged in"
fi

echo "</BODY></HTML>"

OK, this script was entered into Notepad on an NT box, and then FTP'd to a UNIX server.  The HTML page is more or less a simple anchor reference to the script.  When I run the script, I get the following error:

/web/beta/cgi-bin/pinglaura.cgi: echo: not found

We're running a Sun server, that should understand UNIX, right? ;)  Our server software is Netscape's Fasttrack Server.  What language is this script written in?  Is it just straight UNIX (as opposed to PERL)?  

I should note that the UNIX server logs off the user if you type "exec pinglaura.cgi."
 
I should ALSO note that sometimes the file comes up as "not found," even though surfing the file directory shows it's there.  I have to repost it before the web browser can even see it.  I've checked both the permissions AND the CGI set up.

I see what julio (the pro that answered the question the last time) was getting at when he told me to add the PATH line, but it didn't work, for some reason.  Do I have to set the directory some other way?

Should the first "ison" be a scalar: "$ison?"  (Although I've tried that, and it doesn't seem to work much better that way.)

Thanks, pros...

Wow, I've been all over this script in the past 24 hours, and nothing seems to work.  So here's an addendum to the original question, what language is this script written in?

The script was written in sh.  The original unix command line processor.  Your system may not have sh installed.(a sh script is sort of like a batch file for dos)  Sh has been replaced by other programs, but most systems have it for compatability.
Another possiblility is that your script is in the wrong direcory or has the wrong extention.  Some servers require CGI scripts to be in a certain direcory or have a certain extention.
Yet another possibility is that the text is in dos format.  be sure to upload your file as a text file in your ftp software.  This will convert it for you.
Another possibility is that the case is wrong.  Unix servers are case sensitive.  I have had this problem many times, because win95 is not case sensitive.
Last possibility is a programming error, but I'm not a sh expert.
But the programming looks sound to me.
