Mulitiple Instances of an application

[dwgi32]

Hi all,

Have anyone encounter a case whereby you start an application once and using ps -ef | grep, it displays a few instances of that application. By pkill that application all of the instances were killed. Please advise!

Well, yes, httpd for example will run more than one instance. You will notice this with other multi-threaded programs too. pkill will kill all instances of a given name.

Thanks for the information. So is there any way to prevent this kind of situation from occuring in a self-coded applcation?

I'm sure there is, but you'd have to ask a programmer what you would need to write to implement this functionality.

Thanks a lot!

Are you saying you are writing a program and you only want ONE process to start?

An application which you write will not start more than one process unless you tell it to. This is not a trivial matter. The same goes with threads which for simplicities sake you can think of as mini processes.
