Print command line output into a text file in Linux (Ubuntu)

Question

I have a C++ program in Linux (Ubuntu) which prints very long output in a command terminal.

How can i copy this output from command terminal directly to the .txt file by Linux command?

Answer 1

您的外壳程序通过输出重定向为您完成此操作：

$ ./a.out > theoutput.txt

Answer 2

In general you type;

command > file.txt

The greater than symbol > redirects standard out to the file.
