    sudo echo "xyz">>/.profile

    and get
    The file access permissions do not allow the specified action.

    How to do it?

    To make a usage listing of the directories in the /home partition. Note that this runs the commands in a sub-shell to make the cd and file redirection work.

    $ sudo sh -c "cd /home ; du -s * | sort -rn > USAGE"

    You need to use

    sudo "echo xyz >>/.profile"

    to get your command to work, otherwise the redirection happens in the current shell, not as part of the sudo command.
