if you want to read the filecontent of a file provide the filename to the awk at the end it read it line by line only to access the specific file inside the awk use FILENAME variable inside awk..(see man page)..

i have done what i was trying to do..

Code:

 
list=`cat /u/Test/programs`;
for line in $list
do
psg "ServTest" | awk -v pgm_name=$line '{
        cmd_name=($5 ~ /^[A-Z]/)? $9:$8
       gsub(/[[:space:]]*/,"",pgm_name)
       gsub(/[[:space:]]*/,"",cmd_name)

                       if (pgm_name== cmd_name)
               { kill = 1;}     
 #further code is for kill if kill = 1                
        
  }'
done

thankss and regards

kill

KILL(1) 						      General Commands Manual							   KILL(1)

NAME

       kill - terminate a process with extreme prejudice

SYNOPSIS

       kill [ -sig ] processid ...
       kill -l

DESCRIPTION

       Kill  sends the TERM (terminate, 15) signal to the specified processes.	If a signal name or number preceded by `-' is given as first argu-
       ment, that signal is sent instead of terminate (see sigvec(2)).	 The  signal  names  are  listed  by  `kill  -l',  and	are  as  given	in
       /usr/include/signal.h, stripped of the common SIG prefix.

       The  terminate  signal  will  kill  processes  that do not catch the signal; `kill -9 ...' is a sure kill, as the KILL (9) signal cannot be
       caught.	By convention, if process number 0 is specified, all members in the process group  (i.e.  processes  resulting	from  the  current
       login)  are  signaled  (but  beware:  this works only if you use sh(1); not if you use csh(1).)	Negative process numbers also have special
       meanings; see kill(2) for details.

       The killed processes must belong to the current user unless he is the super-user.

       The process number of an asynchronous process started with `&' is reported by the shell.  Process numbers can also be found by using ps(1).
       Kill  is  a  built-in  to  csh(1); it allows job specifiers of the form ``%...'' as arguments so process id's are not as often used as kill
       arguments.  See csh(1) for details.

SEE ALSO

       csh(1), ps(1), kill(2), sigvec(2)

BUGS

       A replacement for ``kill 0'' for csh(1) users should be provided.
