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

If you want to remove the first n leading components of the file name, you need strip-components. So in your case, on extraction, do

tar xvf tarname.tar --strip-components=2

The man page has a list of tar's many options, including this one. Some earlier versions of tar use --strip-path for this operation instead.
