I know everyone probably knows this, but I’m noting this here, more for my benefit than other people’s.
Consider the following (addled Alzheimers programmers are familiar I’m sure…) About to write a new script but sure that you’ve done something similar.
In my case, with the GPS and text message stuff I do, I’m always doing date conversions.
Grep is your friend – in a terminal, type
$ grep -rl "datetime" /home/daniel/Documents/dansdocs/python/danPython
And hey presto, there’s a list of the files that mention “datetime” or any other string you care to try.
