Asp Forum - get process id by using it's name.

? ??

3/24/2009 7:52:00 AM

Hi, folks.

first )
I have a question to get a process id by using it's name for all
platforms.

second)
If I want to kill some processes by it's name, are there efficient way
to do it for all platform?
For a solution for this problem, I am now using the following way ;)

ex)

lines = $x{ ps -Au${ENV['USER']} }.split("\r?\n")

lines.each do |line|
if line.match(process_name)
pids << line.strip.split[0]
end
end

count = 0
pids.each do |pid|
%x{ kill #{pid} }

count += 1 if $?.existstatus.zero?
end

print "total terminated processes : %d" % count

but, this way depends on only unix platforms.
moreover, I am not sure that all platform's output of "ps -Au" are same.

Try sys-proctable gem.

I know the sysproc library supports very good interface for this kinds =20=

of jobs.

but, sysproc doesn't support aix platforms.

$> rake test
(in /home/jykim/sys-proctable-0.8.0)
checking for rb_pid_t in ruby.h... yes
This platform not currently supported. Exiting...
.....

I need pure ruby lang based libraries or all platforms ported things :)

gamsa haeyo~

Since you seem to have access to an aix machine, I'm pretty sure it'll
be easy to add aix support. I doubt the calls needed are much
different than the other unix-based machines.

yes, I also believe that is the best option for me :)

anyway, thanks for all.

I don't have access to an AIX machine, but this might get you started on
a port for sys-proctable:

http://cpansearch.perl.org/src/DURIST/Proc-ProcessTabl...

There appear to be 2 variants for AIX, so I'm not sure which one Dan is
using, but perhaps they'll give you some ideas.

Regards,

Dan
