Here is some code to get you started. It is all untested and guaranteed
to have mistakes:

#!/usr/bin/perl
use strict;
use warnings;

if( @ARGV <= 2 ) {
print "Usage: $0 \n";
exit;
}

>

my( $table, $config_file, $config_file_2 ) = @ARGV;

>
> source $config_file

do $config_file or die("Can't do $config_file: $!");

>

if( $config_file_2 ) {
if( -f $config_file_2 ) {
do $config_file_2 or die("Can't do $config_file_2: $!");
}
}

if( ! -d $backup ) {
mkdir $backup or die("Can't create $backup directory: $!");
}

(similar)

(Where do $UID, $PSW, and $SVR come from? $UID looks like user id and
Perl has built-in $< for that. If $PSW and $SVR are environment
variables, you can get them from the %ENV hash as $ENV{PSW} and
$ENV{SVR}.)

system(" bcp $DB..$table out $backup/$DB/$table -c -U$< -P$ENV{PSW}
-S$ENV{SVR");

(read modify_rename_table.sql file, modify, and call system to run
runsql perhaps)

(Are you starting over?)

[rest snipped]

Good luck!
