How do I exclude absolute paths for tar?

Question

I am running a PHP script that gets me the absolute paths of files I want to tar up. This is the syntax I have:

tar -cf tarname.tar -C /www/path/path/file1.txt /         


        

Answer 1

For me the following works the best:

tar xvf some.tar --transform 's?.*/??g'

--transform argument is a replacement regex for sed, to which every extracted filepath is fed. Unlike --strip-components, it will remove all path information, not just fixed number of components.
