I have 2 python scripts: examples of a producer and a filter,
respectively:
#! /usr/bin/env python
import sys, time
if __name__ == "__main__":
while True:
sys.stdout.write("hello.\r\n")
time.sleep(0.000001)
#! /usr/bin/env python
import sys
if __name__ == "__main__":
line = sys.stdin.readline()
while line:
sys.stdout.write(line.upper())
line = sys.stdin.readline()
I wish to use these programs in Bash, like so:
$ ./producer.py | ./filter.py
However, the producer's time delay makes this not work. If I remove
or reduce the delay, it works. In reality the producer has an
unavoidable one-second delay. I do NOT want to use popen or its
cousins because I want flexibility from the command line; I have many
filters. Is there any way to write the filter to make this work?
thanks,
!!Dean
