    Id like to create a cron job to grab RSS and store locally. There's some spurious content at the start of this xml, so Id like to strip it out. How do I take the results of a wget, pass to a tr and store the file locally. I have a feeling Im almost there:
    wget http://example.com/rss.xml | tr -cd '\11\12\40-\176'

    Any ideas?

    First off wget saves to a file, so you need to either act on the file or set STDOUT to the pipe eg. 
    wget  -q -O - http://example.com/rss.xml

    Then if your tr command works you're in business

    super, set me on the right track.
    wget  -q -O - http://example.com/test.xml | tr -cd '\11\12\40-\176' > output.xml

    seems to do the trick.
