Code:
#!/bin/bash
 
mysub(){
if [ $1 -eq 0 ]
 then
  echo "NO CHANGES ARE NEEDED"
  exit
 else
  sed -i '1i'"$2" $3
  echo "ADDED HEADER"
 fi
)
 
zcat 2013-12-26_file1.csv.gz > 2013-12-26_file1_tmp.csv
cat 2013-12-26_file1_tmp.csv | sed 's/$/\r/' > 2013-12-26_file1.csv
grep -q "TIMESTAMP" 2013-12-26_file1.csv
mysub $? 'TIMESTAMP|id|Fisrtname' 2013-12-26_file1.csv 
 
zcat 2013-12-26_file2.csv.gz > 2013-12-26_file2_tmp.csv
cat $2013-12-26_file2.tmp.csv | sed 's/$/\r/' > 2013-12-26_file2.csv
grep -q  "ADDRESS" 2013-12-26_file2.csv
mysub $? 'ADDRESS|ID|NAME' 2013-1-26_file2.csv

Now, you can go farther, capturing file stub name by grinding it off with ${name%%.*} and suing the stub to make new names. You can pipe together stuff so you do not have intermediate files. You can take many input files from the command line or stdin.

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a    Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
