Problem
When I tar a directory in OS X Lion:
tar -cf foo.tar foo
It produces an extra file ._foo in the tarball:
._foo foo
Cause
The extra file “._foo” is a Mac OS resource fork
It is created by tar on Mac OS X (Lion and earlier versions)
Solution
Set environment variable in your shell, before executing the tar command
COPYFILE_DISABLE=1 tar -cf foo.tar foo
