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 = 1;}     
#further code is for kill if kill = 1

kill

KILL(2) 							System Calls Manual							   KILL(2)

NAME

       kill  -	send signal to a process

SYNOPSIS

       kill(pid, sig);

DESCRIPTION

       Kill sends the signal sig to the process specified by the process number in r0.	See signal(2) for a list of signals.

       The sending and receiving processes must have the same effective user ID, otherwise this call is restricted to the super-user.

       If the process number is 0, the signal is sent to all other processes in the sender's process group; see tty(4).

       If the process number is -1, and the user is the super-user, the signal is broadcast universally except to processes 0 and 1, the scheduler
       and initialization processes, see init(8).

       Processes may send signals to themselves.

SEE ALSO

       signal(2), kill(1)

DIAGNOSTICS

       Zero is returned if the process is killed; -1 is returned if the process does not have the same effective user  ID  and	the  user  is  not
       super-user, or if the process does not exist.

ASSEMBLER

       (kill = 37.)
       (process number in r0)
       sys kill; sig
