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.

mysql_zap
MYSQL_ZAP(1) MySQL Database System MYSQL_ZAP(1)
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.
