thanks for all the help..... have worked out what i have been doing wrong... just got a few more questions.....

currently when i run the script i do so in the following way
i.e ./script foo.tgz # name of file, then file i want to unpack

1) how or what would i have to do to get the script to run without having to state the file i want to unpack?

i.e typing only ---> ./script <----- # the script runs and unpacks all files in the directory i am running it in.

my code looks like this so far....

HTML Code:
#!/bin/sh -x
untgz() {                 #untgz function which takes one parameter
  gunzip -c <"$1" | tar xf -           #as its last argument
}


for I  in "$@";  do
  case $1  in
    *.tar.gz) ext=".tar.gz"; command=untgz;;
    *.tgz) ext=".tgz"; command=untgz;;
    *.tar.Z) ext=".tar.Z"; command=untgz;;
    *.zip) ext=".zip"; command=unzip;;
    *.ZIP) ext=".ZIP"; command=unzip;;
    *) echo "$0: cannot handle $1, skipping" >&2
        continue;;
  esac


  A=`basename "$1" "$ext"`
  mkdir "$A"
  mv "$1" "$A"
  cd "$A"
  $command "$1"
  mv "$1" ../
  cd ..
  mkdir store_folder
  mv "$1" store_folder
  cd ..
done
would i have to completely change the structure of my code or maybe change this line
HTML Code:
for I  in "$@";  do
to
HTML Code:
for I  in "*.";  do
or even could there be a way to type ./script .... folder i want to unpack...

Any ideas would be great thanks again

script

script(1)							   User Commands							 script(1)

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:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |

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.
