Using Python in a Linux Terminal

Question

Okay, so, I just have a quick question regarding python and linux.

I have a program that collects and outputs data to stdout indefinitely. I need to parse this data, and I have a python program I wrote that will do just that. However, I cannot save this data to a file first, as it produces far too much output to save to disk. Is there any way to use redirects to somehow pipe this output into the program?

Example:

python parser.py < ./dataCollector.sh

Close, but you want an actual pipe not a shell redirect:

./dataCollector.sh | python parser.py

Yep! That worked, mostly. I figured it would be that actual pipe, but I always forget that the input program goes first. However, my script basically sets up another program, and that program's output is what I need. It seems when I parse this input, it is just the logging info from the script.

Oops. It did actually work, I was just breaking my loop on a newline... facepalm Thanks for the help!
