as u can see .. many process has the same name but different PIDs .. why is that? is there any problem?? is it ok if i killed all of the (duplicated) processes and leave only one running?
thanks

Not problem all is normal....

Murshed,

Glad you asked your question ... based on the question you asked, I would recommend you do some reading online and get a little more familiar with how Linux works!

http://www.oreilly.com/openbook/

is a good place to start.

thanks alot:)

parent processes spawn children -- which have unique pids ... the can also start other processes....

to see this link us

ps -auxf

the f turns on forest view -- which will show how the processes are related.


For example

thanks:)
thats something new
