I have a lot of XML files, over 50000 of them.

In some XML files, some files are written like this

<filename>abc.JPEG<^Lilename>

^L is just one character, but I can't find what ^L means with Google.

When I use cat to print the content of a file, it shows like the following

<filename>abc.JPEG<
                   ilename>

Anyway, I want to change <filename>abc.JPEG<^Lilename> to <filename>abc.JPEG</filename>

I already found some command to change a word in many files, such as

find . -exec perl -pi -e 's/[find_word]/[change_word]/g' {} \;

But that command doesn't work in my case, because it cannot recognize the search word when I just type ^L.

How can I change <filename>abc.JPEG<^Lilename> to <filename>abc.JPEG</filename> in many files?

I am trying to use CPAN, but I am running into an issue. First I did sudo apt-get install perl. It says it's there. I typed cpan install automatically yes sudo which indicated as done, and I can get into cpan. I downloaded the .pl I wanted to use on CPAN, pointed to the directory, and tried perl file.pl. I am presented with this message:

Can't locate CAM/ODF.pm in @INC (@INC containes /etc/per/ /usr/local/lib/perl/5.14.2 /usr/local/share/perl/5.14.2 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.14/ .usr/share/perl/5.14 /usr/local/lib/site_perl .) at file.pl in line 7

I downloaded CAM-PDF-1.59.tar.gz, double clicked, and tried placing the contents in /usr/local/lib/pkgconfig, but I am getting you don't have the right permissions.

How should I install CPAN on Ubuntu 12.10 (Quantal Quetzal) to use in the terminal? Where am I going wrong?

I was attempting to upgrade my Perl modules through CPAN, but I did not supply a regex/module name to upgrade: perl -MCPAN -e 'upgrade'; I can only assume the worst (which seems to be supported by the output of perldoc perllocal), i.e. all Perl modules from CPAN are installing.

How can I undo this mess? I suppose I can remove /usr/local/share/perl, but what are the implications of that?

Edit: I still have 95% free space on my hard drive, so it's not a huge concern. I just don't want lots of unnecessary clutter. I'm considering rm'ing that directory, doing dpkg --purge perl and redoing the apt-get and CPAN install process. But is it really necessary, or can I just remove the unnecessary modules from /usr/local/share/perl?

The Perl package is in /usr/bin and is an older version (5.12.4). The current stable release appears to be 5.14.2.

How do I update this version? Root access is required, and I do not want to compile new binaries to install in a directory that is in my path.

After a clean Ubuntu Server install, I get the following error when running 'perl'. 

perl: warning: Setting locale failed.
perl: warning: Please check that your locale settings:
    LANGUAGE = (unset),
    LC_ALL = (unset),
    LANG = "en_CA.utf8"
    are supported and installed on your system.
perl: warning: Falling back to the standard locale ("C").

Where should I set my locale, system wide and user specific? If there's a command line utility to do it I'd rather use it than manually edit configuration files.
