how to force to redirect the message on the screen?

Question

Hi, I am running a C++ program and there are other underling code.

When I run it, suppose it is a.exe, there are a lot of information printed on the screen. I can't redirect some information to a .txt file like ./a.ext > temp.txt

How can I force it is redirect to the temp.txt?

Thanks!

Answer 1

POSIX

Reditect STDOUT and STDERR

./a.ext &> temp.txt

Or you can use equivalent from windows format.

./a.ext >& temp.txt

---

Windows (Reditect STDOUT and STDERR)

Reditect STDOUT and STDERR

./a.ext >& temp.txt

More information about this you can find at Using command redirection operators at Microsoft Technet

Answer 2

Some of the information may be written stderr. In order to catch both stdout and stderr, you should use

./a.ext > temp.txt 2>&1
