Command Prompt - outputting results without overwriting target file

Question

I have a situation where I output results from a CLI program:

e.g. input.exe > output.txt

Although output.txt already contains text, by default it gets overwritten when using the command above, how can you write the output to output.txt without overwriting existing data?

Answer 1

Use the >> operator; it appends the output to the existing content of the file.

input.exe >> output.txt
