Even though you edited that, I'm still going to post this because Linux Quiz is for learning after all right?

Your proposed answer formally debated before your edit.

DESCRIPTION

      lpq  shows  the  current print queue status on the named printer.  Jobs
      queued on the default destination will be shown if no printer or  class
      is specified on the command-line.

      The  interval  option allows you to continuously report the jobs in the
      queue until the queue is empty; the list of  jobs  is  show  one  every
      interval seconds.......................

The correct answer is lpc

NAME
    lpc - line printer control program

SYNOPSIS
    lpc [command [argument ...]]

DESCRIPTION
    lpc is used by the system administrator to control the operation of the
    line printer system.  For each line printer configured in /etc/printcap,
    lpc may be used to:

          o  disable or enable a printer,

          o  disable or enable a printer's spooling queue,

          o  rearrange the order of jobs in a spooling queue,

          o  find the status of printers, and their associated spooling
              queues and printer daemons...................

Thanks, I was wondering about that.

I looked at the man pages after I posted because I wasn't sure, but both pages said stuff about queue so I just took it out. :">

Actually it's 255.255.255.255 (you cant actually use it though)

32 bits for full address, divided by 4 sections = 8 bits per section.

11111111 (binary) = 255 (decimal)

@leftism:
It's 255.255.255.254, and the 300s were an inside joke. :P

That'll be why I didn't get the joke then :)

255.255.255.255 is still a 'legal' (you cant use that range as its reserved) IP address, it would just be a broadcast address.

If you have these files in your home directory...

How can you delete the C source files and the header file only, using just one command?

I hate to do this, but do you run Debian?

And I could have swarn your initial question was:

What is epoch and not When is.

But I suppose since I see no sign of an edit then I am wrong. Or am I?
