Create Tar file with a new prefix directory

[keydrive]

Hi,

What is the cleanest way to create a tar with a prefix directory in it?

cd /export/home/testbed
tar -cvzf test.tgz *

I need the tar to include "jump"/testbed/<files> in it not just testbed/<files> in it.

There are sed commands out there but I am in search of a cleaner way.

Thanks

what do you mean by 'cleaner way'?

mkdir testbed
cd testbed
tar xvfz ../test.tgz
cd ..
tar cvfz test-newt.tgz testbed/*

maybe you even could end with: rm -r testbed

"cleaner way" meaning the least amount of code.

Can the structure within a tar be changed?

directory testbed contains files and subfolders. The directory testbed name needs to be tared with a new name testdone rather than testbed. i.e.

testbed/testing/tester/
to
testdone/testing/tester/

I don't see an option in tar man or online to change or modify the path inwhich the tar is stored.

i do not think that this is possible without temporarily extracting files from the tar-archive
