Shell script to check files if exist else touch the file
Hi All,
Thanks in Advance

I wrote the following code

Code:
 if [ $VERSION == 1.1 ]
    then 
       echo "version is 1.1"
       for i in "subscriber promplan mapping dedicatedaccount faflistSub faflistAcc accumulator pam_account"
       do
           FILE="SDP_DUMP_$i.csv"
           echo "$FILE"
           if [ -e "$FILE" ]
              then
                echo "$FILE Exists"
           else
                echo "Creating $FILE"
                touch $FILE
           fi
           i=`expr $i + 1`
       done
 else
     echo "version is wrong"
 fi

there are some 8 files in the directory
Code:
DUMP_accumulator.csv
DUMP_dedicatedaccount.csv
DUMP_faflistAcc.csv
DUMP_faflistSub.csv
DUMP_mapping.csv
DUMP_promplan.csv
DUMP_subscriber.csv
DUMP_pam_account.csv

it has the common prefix "DUMP_" and suffix as ".csv"
so i used a for loop to check for matching the filenames
but i am getting error in touch command as

Creating
touch: missing file operand
Try `touch --help' for more information.
expr: syntax error

and also error in expr

and the extension .csv is not appending to the files
and its creating only DUMP_subscriber and other files without extension .csv

Kindly assist

CPANPLUS::Shell(3)					User Contributed Perl Documentation					CPANPLUS::Shell(3)

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.
