How do I exclude absolute paths for tar?

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 /www/path/path2/path3/file2.xls

When I untar it, it creates the absolute path to the files. How do I get just /path with everything under it to show?

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.

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.

If you don't know how many components are in the path, you could try this:

DIR_TO_PACK=/www/path/
cd $DIR_TO_PACK/..
tar -cf tarname.tar $(basename $DIR_TO_PACK)

You are incorrectly using the -C switch, which is used for changing directories. So what you need to do is:

tar -cf tarname.tar -C /www/path path/file1.txt path2/path3/file2.xls

or if you want to package everything under /www/path do:

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

You can use -C switch multiple times.
