Thanks, but this is exactly the case that introduces subtle problems. It doesn't help if there is another file in the archive, with the same name but in a different directory.
Like here: === mkdir -p dir echo member1 > member1 echo member2 > member2 echo "member1 in directory" > dir/member1 gnutar cf test.tar member1 member2 dir gnutar xOf test.tar --wildcards --no-anchored member1 > member1-extracted === There exists no general way to extract precisely the root member1, which at the same time supports archives with "./member1" path. We can tailor a command line to a specific archive, but this doesn't solve the general case.
