Re: Proper list for 'at' command questions?

    Can anyone suggest the proper mail list to ask questions regarding the
    'at' batch commands? 

I am not sure if there is any GNU version of `at' yet.  You should be
able to use whatever package commands your system uses to discover what
package it belongs to, and then the package information should tell
where it came from.  For instance, on my Red Hat system, rpm -qli 
gives a bunch of information about it.  (It seems RH itself might have
written it; not sure.)

HTH,
