Fork and Exec Linux Programming

Показать описание

Demo using fork and exec to run an executable from disk in a new process. Show how to pass arguments, wait for child to complete, and how to spawn multiple children. Shows advantage of using multiple processes over a single process in terms of using CPU power of multiple processors (cores).

Nice tuts, but I still have a few questions:
0.what happens if you allocate memory on the heap before calling fork and exec?
1.how can I communicate between the parent and the forked process (beyond just getting child's return value)
2.i forked my program, and exec'ed some other binary(from the child). the binary prints stuff out to the cli. Can I get its output from the parent code? Is popen() better suited for that kind of stuff?

Hi sir, Hope you are good, have doubt in threading, can you help me. how can i get in touch with you regarding the same, Thanks

what if one of the arguments passed in is "&" so that it is a background command when doing bash arguments? does exec recognize this?

gilberthernandez

Sir! I have a scenario.. Can we take inputs using exec system call?
As fork() returns two values, then how we are going to return those two values using exec(). If it makes sense, Please do a short program on execlp() taking two inputs from user and returning two values(one to the child process and other value to the parent process).. and it actually performs a task there like making a directory or pings for a website etc.

Regards!

is there any way to make the fork even faster?

Excellent tutorial man, thank you so much

Thank you so much for the tutorial, it is really helpful. :D

neochen

Thank you very much, is there a way to make the children do different tasks for example I want one to sort and the other get the sum or average and so on ? Thank you

muhanad

I cant understand why the parent need to wait for the child or the program would never end. It is the part around 8 mins.

nice tut, is this donald sutherland ?

Ugh I hate how none of these videos go into any detail. Can't one of them at least describe more complex trees
