Ubuntu :: Switch Back To /usr/bin/perl After Installing Second Perl?
Aug 14, 2010
I recently reinstalled the B module for perl. Now I found out it didn't just do that, it installed a whole new copy of perl into /usr/local/bin/perl. When I type 'which perl' at the terminal, it says '/usr/local/bin/perl' instead of '/usr/bin/perl'. Normally, this wouldn't bother me. But I installed the one in local/bin without threading support. The one that comes with the system already is build with threading support, which is why I want to switch back to the system perl, and possibly remove the one in /usr/local/bin.
So how do I change it so that the result of 'which perl' returns as '/usr/bin/perl'? And what do I have to do to remove /usr/local/bin/perl?
The reason I need threading support is because I'm designing a file copier that copies several chunks of a file simultaneously to speed up the copying process. Guaranteed a useful script if it works.
I am new here and want to lern CentOS. Current I have installed CentOS 5.5 x64 and Perl 5.8.8. Now i have install Perl 5.12.1 which located to /usr/local/bin/perl. But how I can move it to /usr/bin/perl so root based on Perl 5.12.1?
I'm new in perl programming and linux OS. What is the difference between perl and perl-devel? What does mean devel? Iwant to install Catalyst and before install as required I have to check if make, gcc and perl-devel are installed in my system. make and gcc are installed. But I have to install perl-devel. First I searched for make, gcc and perl-devel in YAST Software Management and search did not find perl-devel. I visited the software.opensuse.org and wrote "perl-devel" and searched. The result was many similar zips with a prefix perl-devel and I can not choose one for needed perl-devel.
I am a newbie in Linux. using RHEL5. and I thought that PHP was the only programming language i need, so i decided to remove perl. I was in the Gnome, and I went to "Add/Remove programs". Then I uncheck everything that has the word "perl". Then it also removed the dependencies.. and now I can't even startx how do i restore back perl and my startx and everything that has gone missing ? i tried to wget perl, and install via rpm, but it says missing libdb.so.2
am creating a perl third party package and using in my other program. If i install the package with standard 4 commands ie.,
1)perl Makefile.PL 2)make 3)make test 4)make install
package has not installed properly. If i try to copy the package to the threads generated by perl -V command, then am able to get install the package, but i want to install the package by the standard 4 commands. I am using 36 bits OS , perl version is v5.8.5 and OS am using is "Red Hat Enterprise Linux AS release 4 (Nahant Update 6)".
I want to connect to MySQL Database installed on RHEL 5 using perl v 5.8.8.The available DBD perl drivers installed on my machine are:DBM, ExampleP, File, Pg, Proxy, Sponge..I downloaded DBD-mysql-2.1012 and tried installing DBD again but got the following error:Can't exec "mysql_config": No such file or directory at Makefile.PL line 167.readline() on closed filehandle PIPE at Makefile.PL line 169.On searching I found that I need to install libz-devel prior to installing driver for MySQL for Perl.
I have a permission to use several CentOS5 computers that are connected to a server where all shared programs sit. Accordingly, all Perl users for example have an identical path to Perl (e.g. /export/user/bin). The administrator suggested I'll install all the programs I need (specifically Perl and Mysql) in my personal space, and then add them to the path before the already installed ones. Accordingly, I could add/change modules without "sudo" privileges, and without changing the global setting.
CentOS and RHEL even though I've been using various Debian/Ubuntu Distros for quite some time. However, I always used to install perl modules via apt-get or, if that did not work, via cpan.In CentOS, I tried installing a couple of perl modules via yum but there are only a very few available. When trying to install perl modules via cpan, the install process usually fails during the make process.I'd prefer to install those modules via the distribution's package manger yum as it's easier to resolve dependencies. Are there any repositories I should add to have more perl packages available? (Where to add further repositories, I just know /etc/apt/sources.list in debian based distros)The other option still would be to install perl modules via cpan. For instance, when trying to cpan install Geo::IP, the output is as follows:
CPAN: Storable loaded ok Going to read /root/.cpan/Metadata Database was generated on Wed, 02 Mar 2011 02:42:03 GMT
If I use "#!/usr/bin/perl" in the beginning of a perl script the script won't work if the script is at all complicated. Simple scripts like "Hello World" works.
But if I use "#!/usr/bin/perl -w" in the beginning all scripts work?
If I don't use the -w this is whats in the logs:
(2)No such file or directory: exec of '/home/test.net/html/cgi-bin/uh/meny.pl' failed
Premature end of script headers: meny.pl
When I use the -w in the script the error-log shows me this.
meny.pl: Name "main::http_path_cgi" used only once: possible typo at /home/test.net/html/cgi-bin/uh/meny.pl line 24.
I'm attempting to set up a GIMP scripts for batch operations on groups of image files. Initially I started reading about the Script-Fu syntax but it looked too convoluted (at least for me, with 15 years of Perl experience at work) in a way it does the simpliest of things so I attempted to use Perl instead of Script-Fu. From reading the docs I see that I need to install "Gimp::Fu" Perl module. I installed "cpan" first, started it and issued the command:
install "Gimp::Fu"
and got a dependency problem:
Code:
cpan[1]> install "Gimp::Fu" CPAN: Storable loaded ok (v2.18) Going to read /root/.cpan/Metadata Database was generated on Thu, 28 Oct 2010 17:30:45 GMT
Here is my problem:I work with the BioPerl project. At first, I installed cpan modules without any problem,(eg.) sudo cpan -i CPAN::ModuleI've a proxy connection (university) and I'd configured my proxy settings correctly: perl -MCPAN -eshellIn the beginning it worked, but I don't know why it doens't work today. Here is the outline:
fernando@fer-laptop[fernando] sudo cpan -i Algorithm::Cluster CPAN: Storable loaded ok (v2.15) Going to read '/home/fernando/.cpan/Metadata'
I Installed perl-doc in ubuntu 10.04 using sudo apt-get install perl-doc,in the same way I installed doc for postgreSQL. How to use perl-doc so that I can get from perl-doc.
I am using Fedora 11 and am interested in starting to use perl. Does Fedora 11 come with perl? If so, how do I invoke it? If not, what is the usual (popular) way of installing and running perl on Fedora 11?

Obviously I want search every .doc file in the current directory, look for the phrase MY COMPANY and replace it with Tonys Restaurant, but I�d rather it be Tony�s (with an apostrophe). perl does not seem to like that. Is there anyway to overcome that? Or should I be going about this a different way? I apologize, but all the Google results were either way over my head and more than I need to accomplish, or they seem to suggest that I can escape the apostrophe, as I�ve done with the spaces, but this does not work.
I just downloaded Tk-804.028 and try to install it (according to the README.linux) but I get:
> perl Makefile.PL /opt/ActivePerl-5.10/bin/perl-static is installed in /opt/ActivePerl-5.10/lib okay PPM for perl5.010001 Test Compiling config/perlrx.c Test Compiling config/pmop.c Test Compiling config/pregcomp2.c
I want the output of this file to be in a column, not next to each ohter. I tired putting a a newline escape character in a few places, but it breaks the script. It is easy in awk, just ls -ltr | awk '{print $8 }'
I really would like Perl Qt4 bindings. The best I could find is this:[URL]The problem is that the sources would not compile, and the RPMs are for 32-bit machines.Is there really no such thing as good Perl Qt4 bindings?
