I have a program which I want to debug gdb. And I want to call a second program to redirect the output to the first program. How this is done in gdb.

I tried it like that:

run -2 < $(python seconde.py)

But that does not work :(

  • Outside of gdb, how would you run the program? prog -2 < $(python seconde.py) or prog -2 <(python seconde.py)? Commented Dec 30, 2015 at 2:02

The solution is: run $(python seconde.py)
