Question

I have a program that requires user input, which I save to a file by using tee:

tee program.in | program

I also have to capture stdout and stderr in another file. This does the trick

tee program.in | program > program.out 2>&1

The problem is that the user input is going to be based on what the program outputted before, so the user has to see the programs output in the terminal.

Any idea on how to accomplish this?

Answer 1

Another, more idiomatic tee :-?, i.e.

tee program.in | program 2>&1 | tee program.out

I hope this helps.
