Re: get process id by using it's name.

I know the sysproc library supports very good interface for this kinds
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 :)

Hi,

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.
