heroku logs --tail doesnt work when the output is sent through a pipe

[RedXVII]

heroku logs -t | cat

This command will not print any new output from the application, effectively ignoring the -t option.

You did't specified file name.

$ heroku logs --t --app demo_app | cat > demo_app_log.txt

@diatmpravin It doesn't print anything in demo_app_log.txt for me.
Besides, I might not want to redirect my output to a file, i used cat because it was the most obvious example, but here I just want to redirect the logs to a binary of my own, and the pipe isn't working.

FWIW, it does appear that heroku --log -t > some_file.log works, and you can tail -f some_file.log | program as a workaround

I'm not able to reproduce this at all. Does heroku logs -t | cat work now? This code has been entirely rewritten.
