[PLUG] shell scripting problem

For things like this, my approach is to turn namefile
into a sed script and then apply that script.  Something
like this:

    for name in `cat namefile`; do
        echo "s/,$name,/,/"
        echo "s/:$name,/:/"
        echo "s/,$name\$//"
    done > sedscript

    sed -f sedscript group > newgroup

If you're feeling brave, you can write that so it doesn't
need any temporary files at all.
