Convert tar.gz to zip

Question

I've got a large collection of gzipped archives on my Ubuntu webserver, and I need them converted to zips. I figure this would be done with a script, but what language should I use, and how would I go about unzipping and rezipping files?

Answer 1

I'd do it with a bash(1) one-liner:

for f in *.tar.gz;\
do rm -rf ${f%.tar.gz} ;\
mkdir ${f%.tar.gz} ;\
tar -C ${f%.tar.gz} zxvf $f ;\
zip -r ${f%.tar.gz} $f.zip ;\
rm -rf ${f%.tar.gz} ;\
done

It isn't very pretty because I'm not great at bash(1). Note that this destroys a lot of directories so be sure you know what this does before doing it.

See the bash(1) reference card for more details on the ${foo%bar} syntax.
