3. Shared memory + Regex
Write two programs:
unsearcher.c:
./unsearcher /shmem_id "regex"
Opens shared memory object with /shmem_id descriptor
Prints all the lines that not contain regex
filler.c
./filler /shmem_id textfile
fills shared memory object with contents of the textfile
it textfile is too large, simply ignore the rest of it
