1. shell 'rc' and 'sudo'

I have just installed the standard Slackware 2.0, now I have two questions:

0/ has anyone compiled the shell rc ??  I tried sunsite.unc.edu but under
        the directory similar to System/Shells/, found only the
        shells like asm, csh, etc.   I have read in the rc FAQ or somewhere
        that rc works under Linux, but where ?

        ( I looked at the Makefile of the original rc distribution and am
        not sure about the options in it)

1/ anyone using the sudo fascility ?  I tried to allow another user to do
        shutdowns and somehow it doesn't work:

# sudoers file.
#
# This file MUST be edited with the 'visudo' command as root.
#
# See the man page for the details on how to write a sudoers file.
#

# Host alias specification
Host_Alias        FOO=darkstar

# Cmnd alias specification
Cmnd_Alias SHUTDOWN=/sbin/shutdown

# User specification
root            ALL=ALL
jj              ALL=SHUTDOWN

---------------
$ sudo 'shutdown -h now'
(null) not found
$

Thanks

5. Can 'sudo' control 'Directory'???

6. Unix platform advice respectfully requested

7. help needed for sudo, can't find sudo.log

9. has anyone ported 'httperf' or 'siege' to AIX 4.3.x?
