    I have a gzip file and want to recompress it with xz
    I tried the following:
    gzip -c -d file.gz.aa | xz -k -7
    gzip -c -d file.gz.aa | xz -k -7 -
    gzip -c -d file.gz.aa | xz -k -7 - file.xz.aa

    I always get: "Compressed data cannot be written to a terminal"

    How can I manage that?
