python程序在终端和文件中的输出结果

Question

i tried this but the command is a python program that has an input "raw_input()"

someCommand | tee someFile

the output stops at the moment when the program asks for the input

Answer 1

There are several ways around this. raw_input() reads standard input ( stdin ) which can be redirected from a pipe, a file, or even another process:

Using a pipe:

echo "some text" | someCommand | tee someFile

From a file:

someCommand < inputfile | tee someFile

From another program:

someCommand < <(anotherprog) | tee someFile

In each case a newline should terminate the data.

Alternatively the python program could be altered so that it writes to an output file as well as the console, but I'm guessing that's not an option.
