Cut Command help

Hi ,
I am new to Unix.I have a shell script whenere I wnat to find if a particular server is running and kill all the instances of it (running on different ports)
script filename to start the srever is say abcd
If i do ps -eaf | grep abc
I get all the instances of srever running .In the out of of above command first filed is UID and 2nd is PID.I am interested in getting the 2nd field only.
I do folllowing
ps -eaf | grep abc
I get

root 9781 6710 99 08:05 pts/3 07:21:16 ./abcd
root 18211 18168 0 11:26 pts/4 00:00:00 vim habcd
root 19174 17533 99 11:49 pts/1 03:37:49 ./abcd
root 19410 17533 99 11:54 pts/1 03:32:40 ./abcd
root 19575 17533 99 11:58 pts/1 03:28:42 ./abcd

To get the 2nd field I do
ps -eaf | grep abc | cut -d \t -f 2
I get
9781 6710 99 08:05 p
18211 18168 0 11:26 p
19174 17533 99 11:49 p

19575 17533 99 11:58 p
28427 17533 0 15:30 p

pts_quit

PTS_QUIT(1)						       AFS Command Reference						       PTS_QUIT(1)

NAME

       pts_quit - Exit from pts interactive mode

SYNOPSIS

       pts quit [-cell] <cell name> [-noauth] [-localauth]
	   [-force]

       pts q [-c] <cell name> [-n] [-l] [-f]

DESCRIPTION

       The pts quit command exits from pts interactive mode.  The command can be run from the command line or interactively, but on the command
       line it does nothing and is therefore of questionable utility.

CAUTIONS

       Prior to OpenAFS 1.4.5 and OpenAFS 1.5.23, the pts quit command was only available on Unix or Linux and when OpenAFS was compiled with the
       supergroups option (disabled by default).  As of OpenAFS 1.4.5 and 1.5.23, it is always available.

OPTIONS

       Although they have no effect, pts quit takes the following standard pts options:

       -cell <cell name>
	   Names the cell in which to run the command. For more details, see pts(1).

       -force
	   Enables the command to continue executing as far as possible when errors or other problems occur, rather than halting execution at the
	   first error.

       -help
	   Prints the online help for this command. All other valid options are ignored.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. Do not combine this flag with the -cell or
	   -noauth options. For more details, see pts(1).

       -noauth
	   Assigns the unprivileged identity anonymous to the issuer. For more details, see pts(1).

OUTPUT

       This command produces no output.

EXAMPLES

       Here is an example of a pts interactive session:

	  % pts interactive
	  pts> quit
	  %
