Help to Modify File Name in each function before calling another function.

I have a script which does gunzip, zip and untar.

Input to the script is file name and file directory (where file is located)

I am reading the input parameters as follows:
Code:
 
FILENAME=$1
FILEDIR=$2

I have created 3 functions that are as follows:

1) gunzip file
2) unzip file
3) untar file


Say suppose the file name received is as follows:
Quote:
FILENAME=mdm_ind_usa.2031.fsacm.tar.zip.gz
I would to modify the file name to "mdm_ind_usa.2031.fsacm.tar.zip" after gunzip is done in gunzip function is called
Now file name should become
Quote:
FILENAME=mdm_ind_usa.2031.fsacm.tar.zip
I would to modify the file name to "mdm_ind_usa.2031.fsacm.tar" after unzip is done in unzip function is called.
Now file name should become
Quote:
FILENAME=mdm_ind_usa.2031.fsacm.tar
and after untar function
Quote:
FILENAME=mdm_ind_usa.2031.fsacm

Help is appreciated in order modify the filename as required.
Please Note: File Name passed to script could have any number of "." and "_". The file name i provided is for example purpose only.
Actually file name would vary.

NAME
service - run a System V init script SYNOPSIS
service SCRIPT COMMAND [OPTIONS] service --status-all service --help | -h | --version DESCRIPTION
service runs a System V init script in as predictable environment as possible, removing most environment variables and with current working directory set to /. The SCRIPT parameter specifies a System V init script, located in /etc/init.d/SCRIPT. The supported values of COMMAND depend on the invoked script, service passes COMMAND and OPTIONS it to the init script unmodified. All scripts should support at least the start and stop commands. As a special case, if COMMAND is --full-restart, the script is run twice, first with the stop command, then with the start command. service --status-all runs all init scripts, in alphabetical order, with the status command. EXIT CODES
service calls the init script and returns the status returned by it. FILES
/etc/init.d The directory containing System V init scripts. ENVIRONMENT
LANG, TERM The only environment variables passed to the init scripts. SEE ALSO
/etc/init.d/skeleton, update-rc.d(8), init(8), invoke-rc.d(8). Jan 2006 service(8)
