wen u do frok in ur code, the pr gets duplicated. so that line wher fork is
invoked is also in both the processes. nw in parent code it will return pid
of child & in child code it will return 0.
getpid will always return the pid of the pr. so obviously it will return pid
of the child in the child
pid=0 for child
then getpid in child???gives child process id???plz xplain

child contains full code, bt it will start execution of the next line after
the fork.
return value of fork is 0 for the child, bt pid of the child in the parent
process.

@Davesh: foo is the file name. Isn't foo frequently used as a file
name in Unix/Linix?

If you can use both, it would be
head -10 foo | tail -6
