I'm having a hard time to reconcile your specification in post #1 with what you show in post #3 - no cp command, no empty .pdy file creation, no cksum method determination, and the fields echoed don't match the ones given in spec nor within post #3

How would you get along with this as a starting point:
Code:
SRC="/data/files_to_transfer"
TGT="/data/final_files"


(
 cd "$SRC" 

for FN in *.txt
   do    read CKS REST <<< $(cksum $FN)
        > "$TGT/${FN%.*}.pdy"
        echo "$FN", $(date +%Y/%m/%d), $(wc -l < $FN), $CKS, "checksum method used" > "$TGT/${FN%.*}.ldy"
        cp "$FN" "$TGT/$FN"
  done
)

This is executed in a subshell so the cd command won't change your parent shell's CWD. And, yes, you're reading correctly - the redirection without a command will just create an output file but won't put anything in.

NAME

       ktkt_warnd - Kerberos warning daemon

SYNOPSIS

       /usr/lib/krb5/ktkt_warnd

DESCRIPTION

       ktkt_warnd  is a daemon on Kerberos clients that can warn users when their Kerberos tickets are about to expire or renew the tickets before
       they expire. It is invoked by inetd when a ticket-granting ticket (TGT) is obtained for the first time, such as after using the kinit  com-
       mand.  ktkt_warnd  can be configured through the /etc/krb5/warn.conf file on the client. In warn.conf, you can specify that you be supplied
       notice, through syslog or terminal or mail, of ticket expiration or to renew the TGT.

FILES

       /etc/krb5/warn.conf    Kerberos warning configuration file
