If I wanted to save output to a file from a command like make, I would do:
make > out.txt
However that stops the output from being displayed on the console window, and only saves to a file.
Is there a way to display output from a monitoring process, or a long make command and save it to a file?
You can use the tee command to send output to the screen and write the same contents to a file.
make | tee output.txt
If you want to append to the target file (like the >> output.txt redirection) instead of overwriting it, you should add the -a option to tee:
make | tee -a output.txt
