Change cp to mv if you want to move your files.

Code:
find . -name '*.tar' | 
  while IFS= read -r; do
    d=${REPLY##*/} d=${d%-*}
    [ -d ./"$d" ] || mkdir -- ./"$d" || exit 1
    cp -- "$REPLY" "./$d/${REPLY#*-}"
  done

If your read builtin doesn't support the -r option, just remove it.

ARPING(8)                                                System Manager's Manual: iputils                                                ARPING(8)

NAME

       arping - send ARP REQUEST to a neighbour host

SYNOPSIS

       arping [-AbDfhqUV] [-c count] [-w deadline] [-s source] -I interface destination

DESCRIPTION

       Ping destination on device interface by ARP packets, using source address source.

OPTIONS

       -A     The same as -U, but ARP REPLY packets used instead of ARP REQUEST.

       -b     Send only MAC level broadcasts. Normally arping starts from sending broadcast, and switch to unicast after reply received.

       -c count
              Stop  after  sending  count  ARP  REQUEST packets. With deadline option, arping waits for count ARP REPLY packets, until the timeout
              expires.

       -D     Duplicate address detection mode (DAD). See RFC2131, 4.4.1.  Returns 0, if DAD succeeded i.e. no replies are received

       -f     Finish after the first reply confirming that target is alive.

       -I interface
              Name of network device where to send ARP REQUEST packets. This option is required.

       -h     Print help page and exit.

       -q     Quiet output. Nothing is displayed.

       -s source
              IP source address to use in ARP packets.  If this option is absent, source address is:

              o In DAD mode (with option -D) set to 0.0.0.0.

              o In Unsolicited ARP mode (with options -U or -A) set to destination.

              o Otherwise, it is calculated from routing tables.

       -U     Unsolicited ARP mode to update neighbours' ARP caches.  No replies are expected.

       -V     Print version of the program and exit.

       -w deadline
              Specify a timeout, in seconds, before arping exits regardless of how many packets have been sent or received. In  this  case  arping
              does not stop after count packet are sent, it waits either for deadline expire or until count probes are answered.

SEE ALSO

       ping(8), clockdiff(8), tracepath(8).

AUTHOR

       arping was written by Alexey Kuznetsov <kuznet@ms2.inr.ac.ru>.  It is now maintained by YOSHIFUJI Hideaki <yoshfuji@skbuff.net>.

SECURITY

       arping requires CAP_NET_RAWIO capability to be executed. It is not recommended to be used as set-uid root, because it allows user to modify
       ARP caches of neighbour hosts.

AVAILABILITY

       arping is part of iputils package and the latest versions are   available  in  source  form  at  http://www.skbuff.net/iputils/iputils-cur-
       rent.tar.bz2.

iputils-101006                                                     12 April 2011                                                         ARPING(8)
