recommended approach
I recommend taking this problem in 3 steps.

Create list.
Create mv commands.
Run mv commands.

If you try to do everything at once, you can encounter many
unexpected results.

So, step1: create a list of the files you want to rename:

find $PWD -type f -print |
grep '[0-9][0-9][0-9][0-9][0-0]' > file_list

Next, inspect the file_list file and make sure that you only grabbed
what you expect.

Then run this script:

awk '{ print $1, $1 }' file_list |
while read a b; do

echo $b | sed -e 's/[0-9][0-9][0-9][0-9][0-9]\.\(...\)$/\1/' | read c
echo /bin/mv $a $c
done |
tee step2

What this does is create a list of mv commands and stores then in step2.
After inspecting step2, to make sure it looks correct...
Run it:

ksh step2

there you go.

dist::zilla::plugin::run

Dist::Zilla::Plugin::Run(3pm)				User Contributed Perl Documentation			     Dist::Zilla::Plugin::Run(3pm)

NAME

       Dist::Zilla::Plugin::Run - Run external commands at specific phases of Dist::Zilla

VERSION

       version 0.013

SYNOPSIS

	 [Run::BeforeRelease]
	 run = script/myapp_before1.pl %s
	 run = script/myapp_before2.pl %n %v

	 [Run::Release]
	 run = script/myapp_deploy1.pl %s
	 run = deployer.pl --dir %d --tgz %a --name %n --version %v

	 [Run::AfterRelease]
	 run = script/myapp_after.pl %s %v
	 ; %p can be used as the path separator if you have contributors on a different OS
	 run = script%pmyapp_after.pl %s %v

DESCRIPTION

       Run arbitrary commands at various Dist::Zilla phases.

CONVERSIONS

       The following conversions/format specifiers are defined for passing as arguments to the specified commands (though not all values are
       available at all phases).

       o   %a the archive of the release (available to all *Release phases)

       o   %d the directory in which the dist was built (not in "BeforeBuild")

       o   %n the dist name

       o   %p path separator ('/' on Unix, '\' on Win32... useful for cross-platform dist.ini files)

       o   %v the dist version

       o   %x full path to the current perl interpreter (like $^X but from Config)

       Additionally %s is retained for backward compatibility.	Each occurrence is replaced by a different value (like the regular "sprintf"
       function).  Individual plugins define their own values for the positional replacement of %s.
