Watching python logs real time while running on webhosting? [closed]

Question

I have a python script that is running on my site \ webhosting. I've activated it by going to the url -> script.py. Is there a way to watch the logs the script outputs the way you'd see in the terminal if you'll SSH -> run python script.py ?

Answer 1

You can use the 'tee' command, which will output to both stdout (i.e. your SSH terminal) and a file at the same time.

python foo.py | tee /tmp/foo.log

Edit: I've just re-read your question. Unless your script actively logs to a file, there's no way of viewing the output. If it does, you can use the -f flag of the 'tail' command over SSH to automatically show additions to the file:

tail -f /tmp/foo.log

Combine this with a 'screen' session, and you can monitor the output and reconnect whenever is convenient. Screen documentation: http://www.cyberciti.biz/tips/how-to-use-screen-command-under-linux.html

Answer 2

Adding the raw_input() at the end of your script will force you to hit enter before the script executes. Then it will show the output in the terminal window. Just remember to take it out when you're done your initial testing.

Or you could output your Python script to a file then just tail that file. Which would be the easiest way.

python foo.py > file
