tar -tf filename.tar
folder1/file
folder1/name
[...]

I'd like to extract file and name to, folder2. Can this be done as a one-liner?

Use -C and --strip-components (See man tar).

I read man tar. Didn't spot --strip-components. nice one –  Felipe Alvarez May 30 '10 at 6:25

tar-1.14 uses --strip-path, tar-1.14.90+ uses --strip-components. Maybe problem here? –  mmv-ru Jun 26 '11 at 7:42
    
I'd upvote this if it gave an example and not just the switches, as the online manual states, 3 argument styles give rise to confusion. –  Iain Jul 22 at 14:45

You can also use the --transform option for a bit more flexibility. It accepts any sed replacement (s) operation.

For example, this is how I extract a Linux tarball to a new directory so I can apply a patch:

tar -xjf linux-2.6.38.tar.bz2 --transform 's/linux-2.6.38/linux-2.6.38.1/'
