No, the ... was just to signal that you'd continue as before from that point on.

Just take out the three dots after "do" and fix the one remaining occurrence of $1 (in the case -- you should have case $I in --) and you should be fine. Oh, and you should either not move the file before unzipping it, and use $command "../$I" (there are no spaces between ../ and $I -- it means unzip the file $I in the parent directory), or move the file to the current directory, and omit the ../

You might want to put in some error checking, too: if the directory you want to create already exists, should it just go there anyway, or perhaps add a suffix to the directory name and try again, for example?

Similarly, if you run it on multiple files, store_folder will already exist at least after the first iteration, but it might also exist after a previous run. If nothing else, you probably want to avoid the warnings from attempting to create a directory which already exists. For that particular case, it's probably sufficient to simply check if it exists already, and only if not, try to create it.

Code:
test -d store_folder || mkdir store_folder

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.
