Programming :: Perl Script Wont Run - No Error
Aug 8, 2010
I've been trying to get the ol' hello world script to run in a browser. From the hours of reading of various pages about this, I cant work out Basically I get nothing at all displayed.
the perl (test.pl):
#!/usr/bin/perl
print "Content-type: text/html
";
print "Hello, world!";
[Code]....
The output: Nothing. no error message either in the browser window or in the servers error log. If I change the path or the file name I get "invalid CGI ref" in the Cpanel error log.
I did get this to work for a brief time, then changed the Perl script and it stopped working. So I went back to hello world and havn't seen it work since. What is going on?

Code:

I've been requested to modify a perl backup script we use which mounts a networked NAS machine. The actual mount command is called inside a system() command. In testing, I can do a test of the return value, so I'm able to tell whether or not I've mounted properly, but I can't make heads or tails out of the return on deliberate errors. (Such as mounting a non-existent box.) I'm displaying the returned value, which is 256 in my tests. The man page for mount listed error messages with values from 1 to 64, but no higher. Am I drawing this error value from the system command somehow? And what would be the best way to determine what this error means?

I'm writing a perl script to remove a test database and part of that is of course getting rid of all files. So I wrote this to do the job:
Code:
This always results in an "Could not open /u00/app/oracle/product/10.2.0/rdbms/dbs for reading: No such file or directory" (that directory is the one ending with the $spfile_dir variable) message, although that directory exists and the executing user has writing rights on it.
The same behaviour if I create the directory array like this:
Code:
The problem does not occur when one of the directories is the only element in the array though. Of course I could copy and paste that part of the script for the second directory, but I don't like that workaround.

I am a newbie on linux and just searching everything about perl scripting and modules nearly 3-4 days. I need a perl script but one of not easy to find on searching google. Okay now I need a perl script which create or recreate (edit) id3 tags (artist, comment, album, year, cover) of mp3 files stored on my linux centos server. I installed MP3::Tag version 1.13 pearl module to my server. I Searched tutorials about how to use it, finally I get through reading id3 tag of mp3 file but not achieve to modify it or create a new id3tag.
These are the details:
I have a mp3 file called 1.mp3 this script will process that '1.mp3' file read its id3tag if there is one, than modify or create id3tag for it by my fix artist name for example:
'1.mp3' files id3 tag details are like this
Artist: Dj xx
Year:2010
Title:yyyyy
Comment:eerwer
Cover: x.jpg
Now via this perl script which uses MP3::TAG I will change it's
artist as YYY
Title:ttt
Comment:cool
Cover:t.jpg
these are gonna be my fixed values. I mean all '1.mp3' file will have same artist based on script value.
The reason of this script is I will share Dj podcasts on my server and Dj's would have upload their mp3's which has got different id3 tags and cover pics. etc. I want to create more organized podcasts of them by the way I would trigger this perl script via Cronjob.

As some of you know that I am new to this forum. I have another problem that I got stuck on. I have this file called "Fib.rbb" and my instructor told us to write an interpreter program by using Fib.rbb.
"You are to write an interpreter in Perl for Rongs Basic Basic (RBB) as explained in class. The BNF description for RBB and a test file called Fib.rbb are part of the RBB.zip file which is available in the Course Documents folder on blackboard. If you call your interpreter myIntp.pl, you would execute the program via perl myIntp.pl Fib.rbb
Code: Print "A few Fibonacci numbers:"

I'm the server guy which is why I don't know this, but were staging a new webserver and we use some custom perl scripts and as were moving the site over for testing, apache is blowing a perl error;Can't locate web.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /home/mcp/htdocs/cgi-bin/newgraph.gif line 11.,Now I can copy that file local, but there are a bunch of things, so the question is how do you globally add a folder to the perl search path

I want to compare 2 files and show the differences in a text file.
For example, if i open File A an B in notepad
File A:

I'm trying to write a Perl script that will go out to a website, log in, pull up a query page, fill-in and submit the query, extract a few specific lines from the query results, and finally place that output into a file. I'm having difficulty with the log in portion. It appears that rather than using the built-in Apache authentication, the developer decided to write their own authentication scheme that uses cookies.
I setup a cookie jar but I'm not certain I'm actually getting and keeping the cookie. When I try to go to a page after the log in page I get an error saying I'm not logged in or my session has expired. Here's the code as I have it thus far.
Code:
#!/usr/bin/perl
use strict;
use LWP;
use HTTP::Cookies;
