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
19410 17533 99 11:54 p
19575 17533 99 11:58 p
28427 17533 0 15:30 p


Instead of
9781
18211
19174
19410
19575
28427

Please suggest whta to do to extract particular filed of a command output.

NAME
script - make record of a terminal session SYNOPSIS
script [-a] [filename] DESCRIPTION
The script utility makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the record is saved in the file typescript. See WARNINGS. The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends when the forked shell exits or when Control-d is typed. OPTIONS
The following option is supported: -a Appends the session record to filename, rather than overwriting it. NOTES
script places everything that appears on the screen in filename, including prompts. ATTRIBUTES
See attributes(5) for descriptions of the following attributes: +-----------------------------+-----------------------------+ | ATTRIBUTE TYPE | ATTRIBUTE VALUE | +-----------------------------+-----------------------------+ |Availability |SUNWcsu | +-----------------------------+-----------------------------+ |CSI |Enabled | +-----------------------------+-----------------------------+ SEE ALSO
attributes(5) WARNINGS
script can pose a security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a privileged user, that is, root. Be sure that typescript is not a link before running script. SunOS 5.11 30 Jan 2004 script(1)
