Python error logs

[chorlton2080]

Hello folks

I run my Raspberries headless and my SSH sessions are usually brief. Too brief to encounter the intermittent errors that seem to stop my Python scripts: I'm therefore in the dark as to the root causes sometimes. I think, though I'm not sure, it may be due to file access conflicts.

The scripts are initiated using cron at boot and typically function for a few hours before failing: because the RPi's are located in a remote location I'm unable to keep remote connection alive for that period to watch the execution of the script and the error unfold (and thus observe the error message).

Does a log file exist for Python runtime errors or can such be enabled in my scripts?

Is this what you need? Running this saves just the errors

Code: Select all

$ python bad_scritpt 2> error_log.txt

and this saves both std output and errors

Code: Select all

$ python bad_script &> full_log.txt

Excellent! Haven't tried it but I've seen something similar before with bash so I'm sure it'll work.

The problem with being new to Linux is that there is so much to remember - and forget!
