I know that

./executable &>outputfile

will redirect the standard output and standard error to a file. This is what I want, but I would also like the output to continue to be printed in the terminal. What is the best way to do this?

Ok, here is my exact command: I have tried

./damp2Plan 10 | tee log.txt

and

./damp2Plan 10 2>&1 | tee log.txt

where 10 is just an argument passed to main. Neither work correctly. The result is that the very first printf statement in the code does go to terminal and log.txt just fine, but none of the rest do. I’m on Ubuntu 12.04 (Precise Pangolin).

    Use tee:

    ./executable 2>&1 | tee outputfile

    tee outputs in chunks and there may be some delay before you see any output. If you want closer to real-time output, you could redirect to a file as you are now, and monitor it with tail -f in a different shell:

    ./executable 2>&1 > outputfile

    tail -f outputfile
