You need bash to redirect input and output in new gnome terminal.
gnome-terminal -e 'bash -c "./program < input.txt > output.txt"'
Pergunta
To clarify the question: I need to open a terminal window, execute a C program (which takes input from a file) and save its output to a file.
I know that if I do "./program < input.txt > output.txt", I'll get what I want.
For some reason, if I do "gnome-terminal -e ./program < input.txt > output.txt", the program opens on a different terminal window, but doesn't take the input from input.txt nor saves the output to the output.txt file.
What am I doing wrong?
