I don't see the write end being closed here

#

There's the one to close it after the fork for the reading process, but you aren't closing the write end from the writing process

execv doesn't return

#

it replaces the process

#

that wont execute

#

because of the execv thing

#

anyways, after the second fork, the parent leaves the write end of the pipe open

#

so EOF isnt triggered

#

EOF is only triggered when all the write ends are closed

#

it gets closed automatically after then program finishes running

#

after the other call to fork, the parent still has the write end open

#

yeah
