Fwd: Re: Fwd: Re: how to call an application in cgi and let it run in web browser

[Xiangli Zhang]

Gunnar:

 

If vi editor cannot be called through perl cgi under web browser, what I can do if i want to call an application in my script. My case is "phrap"- a perl application, which can be used like phrap fasta1 at terminal to generate several text files.

 

Thanks a lot,

 

justin

This is a better way to run another Perl program:

    eval "require 'test1.pl'" or die "Couldn't require test1.pl: $@";

system("phrap fasta1");

system("vi test.pl");

    system("phrap fasta1") == 0 or die "'phrap fasta1' failed: $?";
    system("vi test.pl") == 0 or die "'vi test.pl' failed: $?";

Following your instruction,

They were suggestions, not instructions. :)

I ran my cgi under internet browser Mozzilla and at terminal.
However, it output correctly for terminal(it automatically open vi editor and open the file "test.pl),

Aha, are you trying to open the vi editor? Then I don't think I'm able
to help you; not sure if it's even possible to do that from a CGI script.

main page"test.pl" [readonly] 6L,
95C#!/usr/bin/perl -w print "Content-Type: text/html\n\n";
print "this is phrap testing file"; ~ ~ ~
~ ~ ~ ~ ~ ~ ~
~ ~ ~ ~ ~ ~ ~ Vim: Error reading input, exiting... Vim:
Finished.  Software error:

'vi test.pl' failed: 256 at /var/www/cgi-bin/jun06_uploadFile.cgi
line 78.

Among all the funny characters, I notice [readonly]. Can it possibly
be that you need to change the permissions for the file to make it
editable by CGI?

But, to be honest, I don't think that's enough. Hopefully somebody
else is willing to jump in and advise.
