Archieving question
 

So I've got an assignment (how true of me :)).
The question is to rearchieve files packed in zip to tar and gzip.
So far I got the script to unpack all the files in the provided directory but repacking them back is a little more of a problem.
So I've got files as follows:
NAME="`basename $FILE`"
HEAD=`echo $NAME | cut -d '.' -f1`
TAIL=`echo $NAME | cut -d '.' -f2 | tr "[A-Z]" "[a-z]"`
so that I could work with the files that end in .zip.
The files get unzipped. But I would like to know the logic of how to remove zip archieve and to gzip the unzipped folders (would be great if no ready solution is given)

The logic is that on Linux the common format for archives is gzipped tar. Working on Linux you will encounter a lot of these archives, which have extension .tar.gz or .tgz. For example most of the source codes are archived in this form and you will find a lot of them referred as "tarballs". Just a suggestion for your task: first manage (create) the tar archive, then take care of the gzip part.

Probably it was my confused explanation. The point is not whether I don't know how to use these archievers it is how do I get the name of the folder that was unzipped so I can use gzip to archieve it.
Without that condition it would have been just the question of using
grep *.zip | unzip
but that way I don't get the name of the unzipped folders.

So I thought about something such as

local PATH=$1 FILE
for i in $PATH/*
do
HEAD=`echo $FILE | cut -d '.' -f1`
TAIL=`echo $FILE | cut -d '.' -f2`
if [ $TAIL == "zip" ]; then unzip $FILE
fi

(yeap not working although could :) work)
and the using variable $HEAD to tar -vcf $HEAD

Something like that.
