Run ksh script from cgi - UNIX for Dummies Questions & Answers

hodges · #1 05-27-2003

Hi,

I'm developing a system which requires me to run a ksh script from within a cgi script. What sort of syntax will I need to do this, I'm sure it's simple but can't find out how anywhere!

Thanks.

In your html you simply place the script you are going to run:

Code:

<HTML>
<HEAD>
<TITLE>Problem-solver</TITLE>
</HEAD>
<BODY  TEXT vlink="black" link="blue" alink="white" >
<CENTER><STRONG>General Answer Generator</STRONG></CENTER>
<p>
Enter a short description of your computing problem in the box.  The program wil
l give back a suggestion on how to solve the problem.
<form name="myform" action=/cgi-bin/gag.cgi> 
<p>
<input type=text name="alertmsg" maxlength="40" size="80"></p>
<input type="submit" value="Submit your problem">
<input type="reset">


</form>
<HR size=2 noshade>
</BODY>
</HTML>

In this case it's gag.cgi which is in the cgi-bin directory.

Then you put your script (what ever language you want to use) in the cgi-bin directory (insure you chmod to allow execution). This is an example:

Code:

#!/bin/ksh
#
echo "Content-type: text/html"
echo
#
#
echo " <BODY>"
echo "<BODY  TEXT vlink=\"black\" link=\"blue\" alink=\"white\" >"
echo "<CENTER><STRONG>General Answer Generator</STRONG></CENTER>"
echo "<p>"
echo " "
echo "`/yourDIR/cgi-bin/getalert $QUERY_STRING'"
echo " "
echo "<p>"
echo "Enter a short description of your computing problem in the box.  The progr
am will give back a suggestion on how to solve the problem."
echo "<form name=\"myform\" >"
echo "<p>"
echo "<p><input type=text name="alertmsg" maxlength=\"40\" size=80> </p>"
echo "<input type=\"submit\" value=\"Submit your problem\">"
echo "<input type=\"reset\" >"
echo "<HR size=2 noshade>"
echo ""
echo " </BODY>"
echo "</NOFRAMES>"
exit

Code:

#!/bin/ksh
#
#
alertmsg="Wow, you stumped me.  Have you tried rebooting?"
alert1msg="Check the web documentation pages for information on the problem"
alert2msg="Check the set up of the computer"
alert3msg="Check for any network issues"
alert4msg="Check for any Change Controls that may have caused the problem"
alert5msg="Hmm, have you tried rebooting?"
#
alert1=`echo $1 | grep -ci unix`
alert2=`echo $1 | grep -ci not`
alert3=`echo $1 | grep -ci network`
alert4=`echo $1 | grep -ci change`
alert5=`echo $1 | grep -ci pc`
#
if [ alert1 -gt 0 ] ; then
        alertmsg=$alert1msg
fi
if [ alert2 -gt 0 ] ; then
        alertmsg=$alert2msg
fi
if [ alert3 -gt 0 ] ; then
        alertmsg=$alert3msg
fi
if [ alert4 -gt 0 ] ; then
        alertmsg="$alert4msg"
fi
if [ alert5 -gt 0 ] ; then
         alertmsg="$alert5msg"
fi
#
exit

I have a related question, somehow I don't know why all my posts to alt.apache.configuration were blocked (no I didn't spam --- and I didn't have ever posted to that newsgroup).

I would like to use a TCL script as a CGI script. However, somehow Apache returns the type as application/x-tcl that prevents it from being handled properly by browsers (marked below).

===========================

cbkihong@cbkihong:~/public_html/cgi-bin> telnet localhost 80
Trying ::1...
Connected to localhost.
Escape character is '^]'.
GET /~cbkihong/cgi-bin/ip.tcl HTTP/1.0

HTTP/1.1 200 OK
Date: Tue, 27 May 2003 10:35:07 GMT
Server: Apache/2.0.43 (Unix) mod_perl/1.99_07-dev Perl/v5.8.0 DAV/2
PHP/4.3.1
Content-Length: 91
Connection: close
Content-Type: application/x-tcl <<<<-------------------

Content-Type: text/html

<html>
<body>
<p>Your IP address is ::1</p>
</body>
</html>

Connection closed by foreign host.

===============================================================

This makes the browser not interpreting it as html and generating a file
save dialog instead, although the script has already been executed and the script
generates the text/html content-type line. How can I make apache use the
content-type line generated by my script instead just like the case for Perl?
