You never check if fork or exec succeeds

The documentation for fork and exec covers this.

You never reap your children.

I meant to provide a link to waitpid, one method of doing this.

i'm not too sure what fork and exec do.

fork creates a clone of the current process.
exec replaces the program being run in the current process with another program.
Check the docs of these functions, and perlipc.
