How to get cpio (gnu, rhel 4) to extract to a specified directory?

Reason is I want to make a tidy script instead of 

cd /some/dir
cpio -whatever<somefile
cd -

    There is nothing in GNU cpio to allow for this. This might be a little cleaner:

    (cd /some/dir && cpio -whatever < /some/file)

    Using the subshell parentheses will preserve the scripts current working directory and using && will ensure that the cpio extraction is only done if you successfully change directories to the target.

  2. Adding a little more to what TCampbell did:

    (cp /some/file /some/dir && cd /some/dir && cpio -whatever < file && rm -f file)
