Linux/Unix shell scripting vs Perl

Hi,
I have general question: i have good working Perl script with .pl extension, and now I have to migrate all to another Linux box, and I was told that I can use only shell scripting, so I'm not sure how different those two things are, will it work without any changes . Is there anything smart I can tell those Unix/Linux admins to convince them to use my old .pl.

I thought that Perl is kind of built in n each Unix/Linux box, another thing that this script will be fired by third party scheduler with currently works with with existing shell scripts, so maybe this can make difference.

Will appreciate any info, I'm knd of beginner.

My pl script pretty simple, something like below, do you think ksh will take it?
--------------------------------------

Code:

opendir(DIR, "$sdir");
  @files1 = grep(/^$name/,readdir(DIR));        # select files with $param name
  @files2 = grep(/\.dat$/,@files1);                # select files with .dat 
closedir(DIR);

foreach $file (@files2) {
  @ports=  split(/_/, $file);                     # extract track
  $port=@ports[2]; 
  @eid=split(/\./, @ports[3]);                    # extract id#
  $id=@eid[0];
  copy("$sdir\$file","c:\:\\Perl\\$targetdir\\$file") or die "Copy failed: $sdir\\$file !";
}

__________________________________________________________________________________________________________________________________________________

NAME

       platform::shell - System identification support code and utilities

SYNOPSIS

       package require platform::shell ?1.1.4?

       platform::shell::generic shell
       platform::shell::identify shell
       platform::shell::platform shell
_________________________________________________________________

DESCRIPTION

       The platform::shell package provides several utility commands useful for the identification of the architecture of a specific Tcl shell.

       This  package  allows the identification of the architecture of a specific Tcl shell different from the shell running the package. The only
       requirement is that the other shell (identified by its path), is actually executable on the current machine.

       While for most platform this means that the architecture of the interrogated shell is identical to the architecture of  the  running  shell
       this  is  not generally true. A counter example are all platforms which have 32 and 64 bit variants and where a 64bit system is able to run
       32bit code. For these running and interrogated shell may have different 32/64 bit settings and thus different identifiers.

       For applications like a code repository it is important to identify the architecture of the shell which will  actually  run  the  installed
       packages, versus the architecture of the shell running the repository software.

COMMANDS

       platform::shell::identify shell
	      This command does the same identification as platform::identify, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::generic shell
	      This command does the same identification as platform::generic, for the specified Tcl shell, in contrast to the running shell.

       platform::shell::platform shell
	      This command returns the contents of tcl_platform(platform) for the specified Tcl shell.
