Hello,

Thanks for the great muLinux product!  I'm using your 'gateway' script in my
ShareTheNet program.  I found a problem with 'dirname', and fixed it.  Here
is a closer approximation of "dirname":
------------------------- cut ---------------------
dirname|*/dirname)

    dirname=`echo  $1 | tr '/' ' '`
    if [ "$dirname" = "$1" ];then
        echo ".";
        exit
    fi

    case $1 in
    /*)     echo -n "/"
    ;;
    esac

    set -- `echo  $dirname`

    if [ $# = 1 ]; then
        echo
        exit
    fi

    while [ $# -gt 2 ]; do
        echo -n "$1/"
        shift
    done

    echo "$1"
    ;;
------------------------- cut ---------------------
And here is a quick script to test it.  Make sure you run this test script
in the same directory as the "dirname" symlink...
------------------------- cut ---------------------
#!/bin/sh
for x in / /x x /x/y/z p/d/q; do
        echo "----------------"
        echo "x=$x"
        basename $x
        ./basename $x
        dirname $x
        ./dirname $x
done
------------------------- cut ---------------------
