I have a fairly large file 1-2GB in size that I need to process line by line
but I first need to convert the file to text using a 3rd party tool that prints
the records also line by line.
I've tried using Popen to do this with no luck. I'm trying to simulate
/bin/foo myfile.dat
And as the records are being printed do some calculations.
pipe = Popen(exttool,shell=True,stdout=PIPE).stdout
for data in pipe.readlines():
print data,
This operation blocks forever I'm guessing it's trying to process the entire
file at once.
