The pty module, reading from a pty, and Python 2/3

[David Hutto]

import sys
import pty
import os

def get_text(filename):
#you need to find the file size, and place it as an integer in read
below, where you return the value
	statinfo = os.stat(filename)

	try:
		( child_pid, fd ) = pty.fork()		# OK
	except OSError as e:
		print(str(e))
		sys.exit(1)

	if child_pid == 0:
		try:
			with open("log.txt", "w") as f:
				f.write("about to execlp")
			os.execlp("cat", "cat", filename)
		except:
			with open("log.txt", "w") as f:
				f.write("could not spawn process")
			print("Could not spawn")
			sys.exit(1)

	child_pty = os.fdopen(fd)
#you have to input into read, how many characters you want read in. if
you place a random integer in, it will read to that integer within the
file
	return child_pty.read(statinfo.st_size)


if __name__ == "__main__":
	print(get_text("my-pty-test.py"))
