hi,
Write a program which takes a single integer argument n from the command line and creates a binary tree of processes, of depth n. When the tree is created , each process should display the phrase "I am process x" and then terminate. The nodes of the tree should be numbered in the breadth-first traversal order. Make sure that that the original parent process does not terminate until all of its children have terminated. This is so that you can terminate the parent and all of the children from the terminal with a Control-C.

thanks

Hi,
Use the command 'trap'


Gustavo.

2 methods :-

1. Use the /usr/proc/bin/ptree command in solaris

2. Get a list of the following type
ps -ef | awk '{print $2 " " $3"}'
This gives you the PID and PPID list of all the processes. Create a binary tree from this using one of the binary tree algorithms.
