How can I release stdin (pass it to the terminal again) after the input pipe is broken?

Question

I want to pipe the output of a command to another command, but I want to be able to type things into stdin like I can without a pipe when the pipe is broken by the first command.

cat file.txt | python -i script.py cat file.txt | python -i script.py will exit the python interpreter immediately when the file is fully processed.

As you are using a.txt file, I suggest another way to process to your demand:

import sys
inFile = sys.argv[1]

with open(inFile,'r') as i:
    lines = i.readlines()

You can call this program by running:

$ python script.py file.txt
