Using awk to kill a process
Hi Guys
I am running a small script to find a process id , ask user if they want to kill the process and then action it Yes or no

Here is what i have

Code:
#/bin/bash


ps -l | grep -i $1 | awk '{print "Process id of '$1' is "$4""}' 

echo "Do you want to kill this process (Y/N)"
read action

if [ $action = "Y" ]
	then
	kill  $4
		elif [ $action = "N" ]
		then
		echo "Ok, thanks for using the program"
		exit 0
fi

Having small problem with the $4 as outisde of the awk command, the $4 means nothing. Is there any way to can take $4 into the if else command to kill it ?

usage for example is ./script gedit
It gives me back the process id of gedit ok but its after that i need a little help

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

																	   KILL(2)
