If its just add SDP_ to existing files then :
Code:
    for i in *.csv
    do
       #FILE="SDP_DUMP_$i.csv"
       FILE="SDP_DUMP_$i"      # otherwise you will end up with e.g.  SDP_DUMP_DUMP_mapping.csv.csv
       echo FILE: "$FILE"
              if [ -e "$FILE" ]
       then
           echo "$FILE Exists"
       else
           echo "Creating $FILE"
           touch $FILE
        fi
        #i=`expr $i + 1`    # You cant add litteral with numeric... (expression error you had...)
        #  and There is not need to increment or change value, for does it automatically... 
     done

CPANPLUS::Shell(3pm)					 Perl Programmers Reference Guide				      CPANPLUS::Shell(3pm)

NAME

       CPANPLUS::Shell - base class for CPANPLUS shells

SYNOPSIS

	   use CPANPLUS::Shell; 	    # load the shell indicated by your
					    # config -- defaults to
					    # CPANPLUS::Shell::Default

	   use CPANPLUS::Shell qw[Classic]  # load CPANPLUS::Shell::Classic;

	   my $ui      = CPANPLUS::Shell->new();
	   my $name    = $ui->which;	    # Find out what shell you loaded

	   $ui->shell;			    # run the ui shell

DESCRIPTION

       This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "CPANPLUS"
       shell.

       Just about all the functionality is provided by the shell that you have loaded, and not by this class (which merely functions as a generic
       loading class), so please consult the documentation of your shell of choice.
