How to read from a .dat file in Unix

Hi All,

I have a .dat file named test.dat where I have stored some process IDs.
Now I need to pick a process ID, one by one and then fire kill -9 for each of those. The logic should be:

1. open file <filename.dat>
2. read until last line of file
3. if process ID is found fire kill -9 <process ID>


Can anyone help me out with the Unix script for this?

Please help urgently.

Thanks in advance,
Sibasish.

NAME
mysql_zap - kill processes that match a pattern SYNOPSIS
mysql_zap [-signal] [-?Ift] pattern DESCRIPTION
mysql_zap kills processes that match a pattern. It uses the ps command and Unix signals, so it runs on Unix and Unix-like systems. Invoke mysql_zap like this: shell> mysql_zap [-signal] [-?Ift] pattern A process matches if its output line from the ps command contains the pattern. By default, mysql_zap asks for confirmation for each process. Respond y to kill the process, or q to exit mysql_zap. For any other response, mysql_zap does not attempt to kill the process. If the -signal option is given, it specifies the name or number of the signal to send to each process. Otherwise, mysql_zap tries first with TERM (signal 15) and then with KILL (signal 9). mysql_zap supports the following additional options: o --help, -?, -I Display a help message and exit. o -f Force mode. mysql_zap attempts to kill each process without confirmation. o -t Test mode. Display information about each process but do not kill it. COPYRIGHT
