I am following a gtk2-perl tutorial, so I wrote the test program, installed gtk2-perl, and got this error:
Code:
Can't locate readonly.pm in @INC (@INC contains: /usr/lib/perl5/site_perl/5.10.1 /usr/share/perl5/site_perl/5.10.1 /usr/lib/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib/perl5/core_perl /usr/share/perl5/core_perl /usr/lib/perl5/current /usr/lib/perl5/site_perl/current .) at ./test.pl line 7. BEGIN failed--compilation aborted at ./test.pl line 7.
I googled readonly.pm, and figured out it's part of some Readonly module.But how do I install it? Preferably using the Arch package manager?

Modification of code I found here. It works, but I don't really know why.
Q1: Why is each filter hit counted only when the conditional is not true?
Q2: I've tried taking the file type, (.old), and put it into a variable for better usability, but then the script fails.
I've been reading / trying to learn some Perl lately. I've found the free book, "Learning Perl", quite good and easy to follow most of the times. However, today I was testing one of the scripts in the book and it would only run partly.
Code:
#!/usr/bin/perl
use warnings;
use strict;
my %inventory;
[code]....
This row is supposed to give option, either to use an additional script as pipe (sort.plx),or STDOUT if the extra script is not found.It works with the other script present, however, with the sort.plx being absent it simply wont use STDOUT instead but whines to me:
Can't open perl script "sort.plx": No such file or directory
Has the author of the original script done some error writing it? Since I'm a beginner and found most of the stuff confusing in Perl either way (having previously only experience in Bash and some in PHP) - I can't really tell for sure , but from what I can read in documentation - it doesn't appear to be wrong.As it looks now, the only way for me to use STDOUT is only by removing:
open (SORT, "| perl sort.plx") or *SORT = *STDOUT;
select *SORT;
rows. But then, I lose the piping in to that other script as an option.
where I'm trying to demonstrate the file locking concept through Perl/CGI.Here is the script which I tried.
Code:
#!/usr/bin/perl -w
use strict;
use warnings;
print "Content-type: text/html

I wanted to find and replace a string from a perl file. I have written a script in bash which runs the following command.
perl -pi -e "s/$findstring/$replacestring/" testfile
where as $findstring = print F_WC_TMP"$line
";
and $replaceString = $line = join ' ', split ' ', $line; print F_WC_TMP"$line
";
But when I am running the above command, i think it is replacing the $findstring with the above mentioned string and hence it contains a $line, it is looking for the variable $line and not finding the exact string. I am confused about how to search for a string that contains $ in it and replace it with another $string.
I'm trying to split a text file into various parts. Everything in between "123" and "break" (including linebreaks) goes into the splitted file.
e.g. using this text file:
This should split into 4 files. However I'm only getting 2 files: one for the line "123break" and one for "123 blah break". The two occurrences that contain linebreaks are being ignored. The .* part of my match should capture linebreaks seeing that I'm using the /s modifier shouldn't it? Even when I use the match /(123 break)/gs it still doesn't capture the first occurrence. I'm using Perl v5.12.3 (from ActiveState) on Windows XP. The text file is also in Windows format.
Code listed below.
The above code generates two files Output_1.txt and Output_2.txt which contain "123break" and "123 blah break" respectively. I want it to generate four files.
I have script that I'm working on that updates a username in all the files that are called blah.inc for my framework. since i host a bunch of these web apps i need to do it to all of them. so I need to figure out how to update these files automagically with out me watching it to call vim every time. heres what I have so far
Code:
This finds the files but now i need to figure out how to do s/bob/fred/g on those files.
I am trying to write a Perl script that can open a file, find text that appears between two identifying strings (for now, "start" and "end"), then modify that text by enclosing it between "term_" and "_term" . Since the identified strings vary, the replacement string becomes "term_$1_term". From looking at other threads in this forum I've been able to get as far as spitting out the modified terms using the following code:
open FILE, "start2.txt" || die ("Could not open file <br> $!");
$text = <FILE>;
while ($text=~ s/start (.*?) end//) {
[code]....
The problem is how to get "term_$1_term" into the file in the same while loop, which I'm guessing would be some of variant of "$text=~ s/$1/$term/;" (which doesn't work as it stands).

I downloaded a Perl script from off a page on the Internet, and tried to run it. It displayed its source in the web browser. First of all, I am in the cg-bin containing my cgi file and the file permissions are set to 755. I open the Terminal in this folder and run ls, which lists my file called hello.cgi; I run hello.cgi, and get a not found error, and run ./hello.cgi and get source code less comments:

Next I open my Synaptic and search for perl, so I can reinstall it. I find nothing. I navigate to /usr/bin and eventually find perl and perl5.xx as well.

So I can see that it can't find libnet-ssleay-perl I bit of searching around leads me to the sources.list file which tells apt-get where to get the packages I think. This is as follows.

View 8 Replies View RelatedI 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.

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
