Thanks Matt,
I appreciate your feedback.
Here's the Perl code for the CGI script:
#!c:\perl\bin\perl
# scrset1_10.pl - Developed: 27/03/2006
# This program is a Client/Server CGI algorithm to display the output
# of a DOS command in the browser. The command is passed to the CGI
# script from a text box.
#
use CGI ':standard';
my $Cmd;
$Cmd = param('txtCommand');
print("Content-type: text/html \n\n");
print("<HTML> \n <HEAD> \n <TITLE> Web-Based Command Prompt </TITLE> \n
</HEAD>\n");
print("<BODY bgcolor=\"#DDDDFF\" TEXT=\"#OOOAAA\"> \n");
print("<center> \n <H1>Web-Based Command Prompt</H1> \n
</center></BR></BR></BR>\n");
print("<DIV>\n");
print("<BR>The output of the command - " . $Cmd . " - is: \n");
print("<PRE>\n");
system($Cmd);
print("</PRE>\n");
print("</DIV>");
print("</BODY>\n</HTML>");
#end of script
Basically, I have a normal HTML page (see code for <!-- scrset1_10.html -->
below,) that contains a textbox (called txtCommand) in a form (frmDetails),
which is used to pass a DOS command (such as 'tasklist') to the CGI script
via form "posting" method, when the submit button is clicked.
The text typed in to the txtCommand text box is accepted to the variable
$Cmd in the CGI script (scrset1_10.pl) . This is then passed to the
system($Cmd); call which is then supposed to output the result of the
command to the CGI-generated page displayed in the user's browser.
The HTML code for the initial form is as follows:
<!-- scrset1_10.html -->
<HTML>
<HEAD>
<TITLE>Web Command Prompt</TITLE>
</HEAD>
<BODY BGCOLOR="#DDDDFF", TEXT="#000AAA",
onLoad="window.document.frmDetails.txtCommand.focus()">
<FORM NAME="frmDetails", METHOD="post", ACTION="cgi-bin/scrset1_10.pl">
<DIV align="center">
<H1>Web-Based Command Prompt</H1><BR><BR><BR>
Enter the DOS command to execute :
<INPUT TYPE="text" NAME="txtCommand" SIZE="20">
</DIV>
<DIV align="center">
<BR>
<INPUT TYPE="submit" NAME="cmdSubmit" VALUE="Execute">
<INPUT TYPE="reset" NAME="cmdReset" VALUE="Clear">
</DIV>
</BODY>
</HTML>
As I mentioned below, this worked as expected when I tested it via WAMP
server (Apache-based), but not on my IIS server.
I tested successfully also, a terminal version of the system call program
from the DOS command line:
#!c:\perl\bin\perl
# scrset1_10a.pl - Developed: 28/03/2006
# This program is a command-line algorithm to display the output
# of a DOS command in the terminal window. The command 'tasklist' is stored
in the variable $Cmd.
#
my $Cmd;
$Cmd = "tasklist";
system($Cmd);
#end of script
Output was as expected.
Again, thanks for your feedback.
Geoff.
