    help with sed


    Ive been trying to use sed to change an output file from a model im working with. The model outputs some data to a text file and for some reason, outputs zero as .0000 , which gives me a probelem with my graphics package (it needs to be 0.0000). Ive tried using sed with the command :

    sed 's/ .0/0.0/g'

    but it doesnt properly work. It changes 0.* to 0.0.* as well! Is there something im missing? Is there a proper way of specifying blank spaces?

    Thanks in advance

    you need to escape the first '.', other wise it matches "any character"
    Code:
    sed 's/ \.0/0.0/g'
